Filter examples (#1868) 

* Allows filtering of examples

* For some reason, the ui designer ignored the courier font family so I manually inserted it into the .ui file

* Allows filtering by file content, too

* Respects dark mode (maybe?), fixes policy setting on code layout

* Prevents "run edited code" from showing unless the actual content changes

* Looks like black font is always best against highlight background

* Left test code in commit...

* Fix broken highlighting on PyQt6

* Address #133

* Better highlighting for both dark and light mode

* Minor refactoring/cleanup, uses combo box instead of checkbox

* Combo box below text edit to avoid clipping
