Scan LivestreamPro source_file to pseudotvlive by creating .strm

+This will scan the source_file of Livestreampro from TVAddons.ag and
ask user whether to add source of not.
+ It has much more robust features(Thanks to Shani) than original
divingmule's livestream in case if you are not familiar with it
+ I understand you already have livestream xml implemented but this is
for Livestreampro. I would be greatful if you include this.
+ It is also ok if you decide not to include it for some reason.
+ Thank you for all the work. You have make xbmc experience much better.
