Updated: mintty-1.1.1-1

mintty 1.1.1-1 is on its way to the Cygwin mirrors. This is a feature release.

CHANGES
=======
Colours:
- Turned up brightness of ANSI bold blue by a couple of notches.
- Allow colours in settings to be specified in X-style hexadecimal
formats such as #RRGGBB or rgb:RR/GG/BB (rather than just comma-
separated decimal).
- Re-rendered the program icon in true colour rather than 256 colours,
with proper alpha channel.
- Fixed a bug where the background erase colour wasn't being updated
when a saved cursor was restored, which caused problems with custom
vim colour schemes.

Mouse:
- Implemented xterm's private mode 1006 for encoding mouse events,
which unlike the other three existing encodings includes the button
number in button release events.
- Fixed off-by-one error in encoding of mouse coordinates in urxvt's
private mode 1015.
- Tweaked mouse handling to make it easier to select a single
character.
- When the right click action is set to extend the selection, a left
click with Shift pressed now pastes the clipboard instead of extending
the selection, as in rxvt.

Compatibility:
- Improved handling of VK_PACKET messages, which tools like AutoHotKey
or AllChars use to send characters, so as to accept characters outside
