cre full text search: fix inconsistencies (#3656)
Fix various inconsitencies: some occurences not highlighted
on displayed page; different occurences highlighted on same
page wheter we went there searching backward or forward; pages
with occurences simply just skipped when searching in one
direction, and not in the other...
To avoid edge cases, crengine will now give back results on up
to 3 pages, that we need to filter.
Bump base and crengine
