Make it possible to load prefs from nightly build by not requiring exactly three components in color dicts

Merge branch 'adhoc_1.0.0.20131209_154745' into v2 (use CTFontDrawGlyphs only when there are combining marks, otherwise use attributed string)

Use NSAttributedString to draw complex chars unless they contain combining marks. This should improve performance.

Fix bug 2744 where nonascii characters would randomly translate or scale by initializing the text matrix in the graphics context

Make the hotkey window go all the way off the screen. It was incorrectly using the screen's visible frame to compute its offscreen position. Fixes bug 2638

Fix bug 2716 where users with dots in the thousands place would lose most of their lines of scrollback

Fix bug 2658 where making a window traditional fullscreen in mavericks would cause another iterm window to become key

Fix bug 2694, which crashes when a dimmed color happens to be the same as a previously used color, and didn't get retained by CRunStorage because it used value equality instead of pointer equality.

Fix a bug where smart selection would include too much stuff before the text to select when there's a soft line break followed by a hard line break followed by the text that should be selected. Drop everything prior to the hard line break from consideration for smart selection.

Fix assert when right-clicking on a line with a lot of double width characters (or, presumably, certain kinds of combining marks) because we computed their screen positions incorrectly.
