[SVN] r10306 (GetBundles)

[Hans-Jörg Bibiko]

improved Error Handling:
- the installation will take place in a temp folder first
- if no error occurred the bundle will be installed
- each error coming from a shell command will appear in the Activity Log
- if one selected more than one bundle to install and an error occurred the installation process will interrupt for safety reasons
- if one error occurred while copying the bundle from the temp folder to the installation folder and there was a folder with the same name, the old folder will be reconstructed
