[JW Lua] MacSymbolFonts/LoadSymbolFonts different sorting

[Jan Angermüller]

Jari,

I noticed that LoadSymbolFonts() uses case-sensitive sorting while the 
MacSymbolFonts.txt is sorted in a non-case-sensitive order.
Probably it's not relevant, but it might be clearer to have the same order.

All the best,
Jan
