This patch allows users to choose which plugins jEdit loads at startup by specifying a PluginSet .xml file through the -pluginset command-line switch.
This is my first patch submission, so it may need a little more testing before being committed.
I am sorry, this totally fell off my stack. I just tried to apply it and now 1 of the hunks fails against jedit trunk.
If you revisit and resubmit, I will make a point of testing it faster this time. sorry about that!
[and there is still a chance of getting it into 4.4 if it works]
