Removed auto install

It was causing problems with the mac process, since the install phase
might not be correct depending on what os you run. So, removed.
Replaced airline with powerline

Since i got powerline setup properly, i figure it makes sense to use it
on both sections. So, powerline it is!
Powerline Quirk, UTF8, and Fish Bin

The powerline call was moved to the end of the file due to an inability
to make it work properly. See the code comment for further details.

UTF-8 is now enabled, for good measure (patched fonts)

The fish bin is different for my mac, so until i figure exactly how i
want to handle the different system locations/etc, i am just hardcoding
the location.
