FlatPlusOperation for future simplifications!

Adding IDENTIFIER Token type with optional differentiation between functions, constants and variables for syntax highlighting.
Adding substitute for many AST elements.
Properly starting builder: parsing identifiers, functions, variables, array values, properties, numbers, strings and subexpressions.

 # Changelog
 
-## v0.5.0 (11 Jan 2024)
-
-**New**
-
-  * New, reworked application icon.

-  * Builtin functions now provide usage when used in the autocomplete of the expression editor.
-
-**Changes**
-
-  * When creating an object that can be positioned, new default behavior is to pick first instead of opening object settings.
-  * Icons with text now use the SVG's text element, allowing them to integrate better with the system's default font.
-  * Special characters popup is now context aware (e.g. no sub/supscript symbols in expressions).
-  * New symbols in special characters popup.
-  * Integrals and derivatives can now be provided with an executable object (e.g. Functions) instead of strings as function.
-  * New description on Linux.
-
-**Fixed bugs**
-
-  * Fixing ∞ 'variable' in domains and expressions.
-  * Several other bugs related to constants in expresions were fixed as well.
-  * Builtin functions now send an error message when not provided with the proper arguments.
-
-**Internal changes**
-
-  * Updated to PySide6 v6.6.1.
-  * Reworked continuous functions' rendering to make it faster.
-  * Removed old bits from an unfinished new parser that weren't used.
-

-**Changes**
-
-  * Fully ported to PySide6 (Qt6).
-  * Greet screen settings are now scrollable.
-  * Changelog is now freezed to current version.

-  * Visual redesign that enhances readability of settings.
-  * There is now a button to hide picker settings.
-
-**Fixed bugs**
-
-  * Cursors in expression are now easier to see.
-  * Symbols in LaTeX rendered Texts cause the LaTeX renderer to crash.
-  * Underscores in distribution names are automatically removed if the name is modified.
-  * Autocomplete categories now properly respect theme colors.

-  * Executable Objects called (like functions, bode magnitures, phases...) now send an error if provided with no arguments.
-  * Function calls with no argument no longer make LogarithmPlotter crash under certain circumstances.
-  * Thank you dialog's lists are no longer draggable.
-
-**Internal changes**
-
-  * A lot of inner changes led by porting to Qt6, fixing a lot of bugs at the same time.
-  * Disabled auto detect of visual theme if the `QT_QUICK_CONTROLS_STYLE` environment variable is set.
-  * (macOS, Windows, Flatpak) Drastically reducing installer sizes (more than halved).
-  * (Launchpad/Ubuntu) Using custom built packages of PySide6, meaning smaller installation and distro dependency.

-  * New completely revamped expression editor:
-  * Automatic closing of parentheses and brackets (can be disabled in settings).

-  * Autocompletion is now available (for functions, variables and constants, object names and properties) (can be disabled in the settings).
-  * Object properties can now be used in expressions (e.g. if you have a point named A, you can use A.x to access its x value).
-  * Executable objects can be now be used in expressions (e.g. if you have a function named 'f', it's accessible using `f(<value>)`).
-  * LaTeX-rendered formulas are now used in the Objects and History tabs when LaTeX rendering is enabled.
-  * Errors in formulas are now reported in message boxes.
-
-**Changes**
-
-  * The Object Editor dialog has been completely reworked internally, resulting in notable performance improvements.
-  * Vast improvements to the objects system: names can no longer be shared amongst different objects.
-  * Disabled access to custom variable and function definition in expressions (can cause issues and vulnerabilities)
-  * When using the set position cursor, the position change is now saved a single history action.
