New editor and patches

Hello

My name is Marcin Raczkowski
I'm developer from Poland, anyway i recently started
programing in ruby
full time, and found this IDE.

anyway i'm working on improving it's usability 

I'm attaching 3 patches that add very usefull feature -
plugin reloading
for faster plugin development 

also one small patch for menu pane that allows removing
items from menu
when plugin unloads

currently I'm working on code completion plugin - it's
preatty advanced
already  makes use of RI and Ripper, but it needs more
work.
