New Plugin: Python extension (and Remote KDE unlock)

[Srivatsan Iyer]

Hi Aleix,

Unlock/lock is just a sample. The main idea is to embed python interpreter
with custom modules, so that anyone can easily write their own plugins. All
it would take is a few lines of python as opposed to a shared object.
Further, the Android activity corresponding to this plugin can potentially
be made generic enough to dynamically show elements corresponding to each
plugin. Currently the ListView gets automatically populated with plugins
information (specifically ones that have expressed an intent to listen to
"MAIN" event  -- akin to android.intent.action.MAIN).

May be providing a different example might help what I'm trying to explain.
Assuming the android device is able to listen to an event "battery fully
charged", any one can quickly write up a script that listens to that event,
and sends a desktop notification to unplug the charger. All you'd need to
do is drop the script (and metadata.json) in a specific folder. That's it.
No change on the android side at all (assumption of being able to listen to
the event still holds but this is just a one time business).
