fixes bug reported by scrawl
1. openmw.cfg had content files in order 'Bloodmoon.esm, Tribunal.esm, Morrowind.esm'
2. Blank_ESM_2.0.esm is in the Data Files directory
3. Do an ini file import.
4. Imported profile will have Blank_ESM_2.0.esm as the game file. Should be Morrowind.esm.
Root cause: Game File combo box and Plugins Grid shared same data model, so changing plug-in file order also changed order of Game File combo box.
1. FileDiaog in OpenCS now shows warning icon beside .esm./.esp files with load order problems.
2. omwlaucher -> replaced "stop" icon with "warning" icon for files with load order problems.
1. Errors found are added to default tool tip text. (Instead of replacing it.)
2. If multiple errors are found, all are shown in tool tip text, not just first one.
3. Load Order Errors are updated when files are activated/deactivated, not just when the files have their position in list changed.
