Jboss Runtime recognition - improvements

relating to JBIDE-6119 I ve found several things in 'Jboss Runtimes; preference page that should be improved.

1. Navigation to runtimes

• When I click 'see Seam Runtime' or the others, whole preferences window get's into Filtered state and there is no way out of it. After navigating I am not able to selec any other preference page except for 'Jboss Runtimes' and the ones where I can navigate to. The only workaround is reopening whole Preferences window, which is not good.
  2. Searching
• I don't like the way it works. After I select directory to search in, whole 'Preferences' dialog freezes for a while (background job with progress listener should be used instead). Then, when it gets alive I can't know what runtimes were found/added. I would expect another window with search results forcing me to select runtimes I am interested in. Then these runtimes would be added.
  3. Export/Import buttons do not work at all, I assume this is correct in current phase of development.
