Support for consolidating manufacturer names

[jueank]

Manufacturer names are spread across 3 (and more) locations:

• Visual Pinball X database file
• Multiple media filenames (playfield screenshots, etc.)
• GameStats.csv

Filtering in PinballY based on manufacturer fails in practice, since manufacturer names happen to be spelled in multiple different ways. This is because of manufacturer names coming from ipdb.org and are maintained there in varying quality, including spelling errors and cases like Midway - Bally (see attached screenshot), sometimes being abbreviated, etc.

Correcting manufacturer names is a tedious task, because it has to be touched in multiple locations. It would be nice if there is support in the way of having a functionality to select multiple manufacturer names and transition them (updating all above locations) into a single spelled one.
