External Song File Sourcing

Added functionality to source songs from user-made song files in addition to or in place of built-in ones

Added sort by artist

Sorting improved in general. "The " is now ignored at the beginning of songs and artists, and things are now sorted after casting to lower case

Added functionality to choose whether songs are sorted by title or artist in preferences

Text Display Preferences Added

Preferences added to make display clearer and add a bit of flexibility. Current options are

-Text display size: Controls the size of song structure text, verse text, and chorus text
-First line margin: Controls the margin of each new line
-Wrapped line margin: Controls the margin of lines that wrap around due to overflow

Added Permanent Scrollbars

Added scrollbar to main menu
Added scrollbar to song verse/chorus text so the user knows when there's more text off-screen

First Fully Functioning Build

Fully completed build with all of the song lyrics currently in my library

Initial Release

Should be fully-working, but doesn't have all of the songs I'd like to add
