Merge branch 'fix-latex-output' into develop
Make quotes in powerline-config --help same as in powerline --help
Make `powerline-config` without arguments show proper message

In Python-3* it used to show the following:

    Traceback (most recent call last):
    File "/usr/lib/python-exec/python3.3/powerline-config", line 66, in <module>
        args.function(pl, args)
    AttributeError: 'Namespace' object has no attribute 'function'

now it shows

    usage: powerline-config [-h] {tmux,shell} ...
    powerline-config: error: too few arguments

in both python-2.7 and -3.3.

Fixes #1120.

Record git hash in dev version
Move all parser definitions to powerline.commands.*.get_argparser()

Reasoning: they will be easier to reach there. It will also be possible to use
specific ArgumentParser class that will just collect data for sphinx.

Update powerline-release script to use live ebuild as the base

Reasoning: I am going to add man pages support to the live ebuild, but it does 
not make sense to add this to the 1.0 ebuild previously used as the base. Since 
new features will likely continue to appear in the live ebuild powerline-release 
script was modified to do the right thing under new circumstances.
