improve Windows command prompt template

Mappings for the Windows command prompt mapped the bright colours to
shades of light/dark, which resulted in weird looking applications.
This new mapping respects the bright colours, and mostly uses the same
colours for the dark and light versions, because the colour schemes do
not have dark and light versions of the colours.

The mapping is optimised for the Solarized scheme. For example, 0F in
Solarized maps perfectly to the purple/pink of cmd, but 0F in other
schemes looks more brown. Brown-ish colours could be more suitable for
the dark red colour of cmd, but Solarized 0F would look stange when
used as dark red. I think this mapping is a good compromise.
Fix highlighted line
Correct Color* keys
shell: detect tmux and send different escape codes

This allows to change the scheme from within tmux.

From the tmux CHANGES (1.5):

  * Support passing through escape sequences to the underlying terminal by
    using DCS with a "tmux;" prefix.

Added Color Space info to iTerm2 templates

When loading colors from the profiles iTerm2 searches for the Color
Scheme key, if that isn't found they are converted to the Calibrated
color space.
Since the colors are defined in the sRGB color space, we need to specify
it, so they are loaded correctly.
