add function to open repo from cmd-line

I work exclusively in a 'Projects' folder in my home directory. I clone
right into it or start repos there. I wanted a way to quickly open up
to the repsitory on github dynamically if I'm between projects.

add function to open repo from cmd-line
update github() to be more dynamic

The function now directs to any repository, regardless of repository owner.

Initially this function only opened files that were under my username, I
found that if I've cloned a respository that I'm working on with somebody
else I couldn't route to that repository the same way.

change solarized settings to dark

I changed to contrast to a darker tone using the 16 color terminal
setting because I find the blue more appealing than black.
add powerline settings

added a powerline settings section to where I enable fancy symbols and a
solarized color theme to match the vim color theme.
