Added new version of c-support.

Plugin is from a new branch which actually works with vundle.

There may be problems with this.  I have "backed up", the c-support
folder from the plugin at .vim/c-support.  Should help to protect
against updates, but may also be a headache.
Minor updates to a few rcfiles.
Major refactoring of install script.

Script now generalizes to holding more than just the config files in my
home directory.
Added secure synergy function to .shellrc
Fixed config file for github

I also added keychain support to .zprofile
Merge remote-tracking branch 'origin/marvin'
Replaced old powerline config with new stock one.

Will merge new and old configs in next commit.

I also added a few more files to the home/dnoland/.config section.  The
main thing is that my roxterm config should now be portable.
Touched up .vimrc to imporve diff support.
Added Git Gutter to .vundlerc
Added ~/.bin to repo.

Personal binaries are now portable!
Navi branch with "old" powerline config.

The recent update does not work with the old powerline config.  Thus my
config needs to be merged with the master branch which has the stock
config.
Trying to make Gbrowse work.  Failing.
Merged old and new powerline configurations
Removed pointless outdated remark from README
Attempting to get powerline tabline to work.

The screen keeps flickering whenever the tabline is on!
Fixed persist undo for vim.

I also removed YankRing as I have determined that it breaks blockwise
visual copy.
