When `upower --enumerate | grep -i BAT` returns multiple lines of results (which are file paths),
the added quotation (from commit 3cb5f3f7e6) concatenates them all to provide an invalid path.
Thus to make the plugin work as before the commit,
take only the first line of the results.
Avoiding the if statements, using exit code of `grep -q` instead.
Reverted the change that adds a space after the AC char. Opting for a
default value, allowing to override from one's profile.
The previous version was printing an error when the battery percentage
was in the single digits, e.g. "7.04%". The code cuts returns the first
two digits, which in the case of "7.04%" are "7.". Any code that tries
to use that, e.g. the powerline-multiline theme will fail with an error.
This change corrects that by zero padding single digits, i.e. "07.04%"
instead of "7.04%".

chmod -x plugins
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.
