removed hcht plugin. there are several bugs which couldn't be fixed so far without rewriting the whole module
added git_stats function to git plugin collection
add support for mactex if its present
make sure tmux is launched in 256 color mode
Unset the MACTEXT_PATH var so it doesn't leak through to env

Thought this variable wasn't making it to the session, but it does even
without the `export`.  This corrects that by explicitly unsetting it
before we continue.
Added dos theme
remove symbolic link to self
Create the concept of enabled plugins

This allows users to disable a plugin without completely removing it.
Instead, they simply remove the `plugins/enabled/*.bash` file for the
plugin they want to disable.  This continues the concept of "everything
on" while providing greater flexibility to future users.

It might be a good idea to allow turning these off by default in the
future and allowing not only the `plugins/enabled/*.bash` files but also
an array of `<plugin_name>` values that would search for
`plugins/available/<plugin_name>.plugin.bash` to enable them.  That
method would make it easier for people custom tune their plugins from
within their `.bash_profile` script.
Merge pull request #48 from tswicegood/cleanup.
