#882 Quick Search for Media, sources and Notes not consistent

[KosherJava]

Typing I1 or F1 into the search box brings you directly to that record even if there is also a I11, I111 etc. It would be nice if this worke for sources (S1), Media (M1) and Notes (N1). The notes might be tricky and does not really have to be implemented since there is currently no standalone page in PGV for displaying top level notes.
The interesting thing is that if I type in S520 it will bring a match but S5 will seemingly search for all sources that start with a 5.
