-Fixed an error where the plugin would not find the new Repositorylocation immediately if you already had another repositorylocation stored.
-Moved the fetching of the contents of Readme.txt into its own thread, where it does the work in parallell, so that it does not tie up the UI-thread.
-Changed some settings in the Wizardpage-layout, to prevent the detailsbox from expanding to fill the entire window if you tried to resize the window after the readme was loaded.
-When a user selects a project to import and presses "Finish", the wizard will now display a progressbar to indicate that it is doing something.
-If the user has entered an invalid URL or an URL that does not lead to a valid SVN-repository, the plugin will now alert the user instead of crashing. Unfortunately, this is also triggered if the user aborts the login-procedure, which is not ideal.
-Tidied up the code, and added some comments.
