*hack hack hack*

Sat down for a while to work on v0.8 of Parcellite and managed to commit some changes to the way actions are executed. I used to use a simple system() call, but in its single-threaded nature Parcellite would become unresponsive until it finished executing your action. I implemented a simple pthread for each action executed so that you may continue to use the clipboard manager as it executes your desired action, something I should have done from the start but oh well :)
