Fix for a bug when in Turkey and Azerbaijan, the names of downloaded objects which contain the letter 'I' do not get translated to upper case correctly (part 2: fix 'toLowerCase()' )

Fix for a bug when in Turkey and Azerbaijan, the names of downloaded objects which contain the letter 'I' do not get transalted to upper case correctly.

If we're updating an object, and it is the current object, reload it immediatelly so that the new version appears by itself.

Bugfix: in addition to deleting the files from local storage, also delete mentions of downloadable-but-now-built-in objects from Shared Prefs.

delete icon, object and extras files from local storage when:

1) we delete a locally produced bandaged 3x3
2) it turns out that a downloaded object is already built-in (which can happen if we download an object and then upgrade to app version which builts it in)

New, generic bandaged 3x3 class 'TwistyBandagedAbstract'.

Now, (almost!) any bandaged 3x3 can be created by extending this class and implementing one abstract method 'getPositions()'. Almost, because there's still one restriction: currently all cubits need to be one of the 5 allowed types: 1x1x1, 2x1x1, 3x1x1, 2x2x1, 2x2x2....

up the number of scrambles of the BAN2 and BAN4 objects to respectively 20 and 22.

solve the 'wasDownloadableButNowIsBuiltIn()' bug in 1.9.6 and 1.9.7.

Make it possible to automatically re-download EXTRAS file if it previously failed to download
