Changes to Assembly Library:
Sorting now works (pivot item is copied for comparison and index comparisons are now signed instead of unsigned).
Menu shadow now looks better on black and white modes.
Sorting is now implemented for File Fialog: directories are displayed before files.
File Dialog now displays directories with upper case letters and files with lower case letters.
Line splitter now removes all empty lines from the end.
