Support for tinting added.

FontManager can now tint characters - change their colours, effectively. If you have a white font, this gives you a multicolour font.

Multiline, tinting and UTF-8
support added.

There are three ways to do it - you can set the tint for the whole string using a method, you can use modifiers to change it (e.g. the e in pulse) and you can put inline colour definitions.

e.g. Hello{blue}World ! This {1,0,0.5}is {} text"

The {} can be set to any pair of bracketing characters that are not alphanumeric or a decimal point.

Both the library and demo have been updated for the new improved library - though the demo is still unchanged.
