Last change on this file since 655 was 655, checked in by jts21, 10 years ago

Switch to using specialised objects for settings so they make more a bit more sense (now each setting is a single object instead of multiple, and setter functions and default values are less hackish)
Also added tooltips (help strings) to settings, will need to add a way of displaying these (maybe add the idea of a tooltip which is a text item which only appears when hovering over another item?)
Converted all settings over to new format, everything seems to be working fine
