Misc fixes
A few miscellaneous changes.
- Cleanup shouldn't happen if an exception occurs to enable easier debugging
- Multiple homepages are now displayed more nicely in search results.
- Nofetch mods display the source url in the error rather than the mod name.
- Added AUX files to manifest (i.e. those in files dir. Not currently used, but will be soon).
