Chrono talent balance

Timey Wimey stuff.  Can you add a commit message from me thanking everyone for all the playtesting and feedback?  Would like the community to get some recognition in the release notes :)

Font.draw convert

Before you ask: yes, yes, I tested it. Not even per-commit, not per-file: I did it change-by-change. Took me a lot of time but I think I caught everything.
Hooray, no more drawColorString in engine.ui!

Small fixes #whatever

Lists want scrollbars to count from 1, and more complicated stuff doesn't really care. So I made them count from 1.

Many a fix to colored string rendering.

Problems found and obliterated:
* drawColorString and drawColorStringBlended were the same. Now they correctly alias one another instead of being letter-to-letter copies. (And they were, I swear.)
* drawColorString used LPEG and Font.size, which also used LPEG. This resulted in extreme double LPEGging of every word. See below.
* drawColorString was word-to-word tstring.drawOnSurface except less powerful and with return value. So I expressed the former in terms of the latter. This also fixed aforementioned problem with using Font.size.
* the same LPEG expressions were used in drawColorString, Font.size, and string.toTString. Now everything uses tstrings.
* TStrings now cache results parsed from strings, so functions that accept fancy strings don't choke parsing them every time. Let me say, this helps.
Results: tremendously improved performance on low-end machines.
