occurrences/texts shows "n lines"; should be "n texts" and should allow switching to different texts.

[tim-band]

scorpion -> girtablilu -> GIR2.TAB.LU2.U18.LU -> Sennacherib 166 21

GIR2.TAB.LU2.U18.LU (occurrences) shows "2 Lines", with these two sources.
Sennacherib 166 21 (occurrences/texts) shows "2 Lines". This is the same two lines as above (maybe? Although it doesn't seem to work like this with scorpion/mer but anyway)

So we should say "2 Texts", and allow prev and next buttons to get between the two texts we could have chosen on the previous page. This is what the P4 pager does.
