Add transactional committing of scores/beatmaps

Browse Source 
This helps slightly with performance, allows better monitoring via realm
studio, but most importantly greatly reduces filesize.

fully compacted:        109M
transaction size 100:   115M
transaction size 1000:  123M
transaction size 10000: 164M
single transaction:     183M

With a transaction size of 100 there is a performance reduction, so 1000
seems to be the best middle-ground.
