UpdateScriptPaths can cause race condition problem

Current process is:

1. Download IMDb+ scraper-script SVN
2. Insert into MovPic database with wrong paths
3. Update paths directly into MovPic

Between step #2 and #3 there seems to be a cache/memory/race-condition issue 
because the database 'scripts' table will contain the right version, but 
MovingPictures ends up using the inserted version with wrong paths.

The 'CheckForUpdate' function @ 
http://code.google.com/p/imdbplus/source/browse/trunk/IMDb%2B/IMDb.cs#598

at line #609 it does step #2 which refers to 'ScraperScriptInstallation' 
function @ 
http://code.google.com/p/imdbplus/source/browse/trunk/IMDb%2B/IMDb.cs#716

It is before line #718 that the 'UpdateScriptPaths' function @ 
http://code.google.com/p/imdbplus/source/browse/trunk/IMDb%2B/IMDb.cs#818 
should be done.

This means the 'UpdateScriptPaths' function has to be rewritten to deal with 
the 'xmlFile' from disk and not MovPic database.
