Fix for jmockit version 1.5 and higher. Class mockit.Mockit does not exi...

Hello ajermakovics

It's me again. We use now JMockit 1.7 and recognized that it needs a fix on the eclipse plugin. The class mockit.Mockit was removed with 1.5. So it is not suitable anymore to find the location of jmockit.jar. I was quite conservative to just another model lookup. Maybe it would be enougth to change Mockit into Mock. But I am not absolutely sure if older versions would still work.

Hope you can accept my pull request and build a new version for workplace. We really like the plugin.

Kind regards
Roman
