Merged PRs for improved windows support, light themes, and ignored git roots

Merge pull request #18 from strangebug/master

Add unix variants hints. Add windows specific implementation.

Introduced a solution that automatically shrinks down the prompt if the shell is low on space, fixed several bugs.

• Introduced a system for shell segment priorities, which, if space is limited, removes segments with lowest priority first. This can be controlled with the -priority flag, with decreasing priority.
• Introduced -maxwidth, specifying the maximum width (in percent) of the shell that the prompt may take up. Default is 50
• Fixed an issue where segment-cwd could read out of bounds

Fixed an issue where in newly initialized repos the git segment would not show the correct branch

v1.3.2

Improved git segment when in detached state or in newly initialized repo

Massively improved the quality of colorize-hostname

These were chosen by taking the color with the highest contrast from

• background with sqrt-inverse of saturation and luminance
• background with sqrt-inverse of luminance
• background with inverse of saturation and luminance
• the color 250 - #bcbcbc

and then finding, via brute force, in Lab colorspace the xterm-256color with the smallest vector distance
