This will allow to open new terminal tabs in the same directory as the
current terminal. Uses the fact that plugins are loaded after the
selected theme. Themes often manipulate the $PROMPT_COMMAND variable.
Implementation inspired by the pathmunge function.
If you had multiple terminal windows open, there was a chance that the command was sent to another window (the one with index 1). Using index 0 will execute it in the currently visible window.
new tab. If you use `export HISTIGNORE=' *'` in your shell, this will
ensure that commands starting with a space will not be included in the
history. Since the command sent to the new tab by the `tab` command
probably shouldn't show up in the history, I added a leading space
character.

cleanup filenames to standardize on x.plugin.bash format
only plugin files intended to be executable from the command line should
contain a shebang line, and should be a+x.
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.
