Multiple instances of a plugin

Let each plugin be run several times with different settings.

If you read #1 and #2 you will understand that you might want to search twitter for both a location AND a tag. that can be solved by using different instances of the plugin. 

allthough i understand this will not solve the issue with tweets from a specific location AND with a specific tag. (tags in borlänge tagged with daladevelop).
