[Mycroft] How can I change the name of my plugin?

[Tautvydas]

Hello!
I made an opensearch plugin. Then I submited it. Later I noticed that there
is another plugin named same as my plugin. So those two plugins can't be
installed both on one browser. Here is a link with plugins:
http://mycroft.mozdev.org/download.html?name=google&category=12&country=LT&language=all&submitform=Search&sherlock=yes&opensearch=yes

The plugin made by Tautvydas is mine. I want to change exactly 'ShortName'
of my plugin so it could be used with that other plugin at the same time.

How can I do that?
