Initial check in of new color scheme system (thanks Gadgetoid)
WIP turned ColorScheme into a singleton so it can be used merrily.
Removed all highlighter defines and code that depends on them.
The cleansing doth continue; more culling of now unused functions; added selectall controls; new changes no longer work with Qt4, but who cares; to the future!
Auto-generate alt colors instead of having to manually set all the tiny variations.
Connected Preferences color setting to main editor colors.
Clean up highlight signaling system; stop direct colorscheme access during background drawing.
Deleted highlightCurrentLine as its preempted by updateBackgroundColors
Prettified highlighter tab in Preferences menu; editor window now repaints as a selection is being made; cancelling the edit reverts any changes; added some themes to test out; removed more dead code.
Updated IIe theme
Added termpaper theme.
Fixed SyntaxText repaint problem.
Added Princess theme.
