Fix bug in detecting text in MenuSearch
A bug sneaked into my implementation of Boyer-Moore-Horspool. This lead
to not finding certain patterns. Given the text 'abcdde' and the pattern
'dd', the faulty implementation would not find 'dd':
1. 'ab' does not match, skip 2 (length of pattern)
2. 'cd' does not match, skip 2 (length of pattern) <- the bug.
3. 'de' does not match, end of string
The bug in step 2 is to not use 'd' to detect how far to skip but to
use 'c' (which is not in the skip-table) and thus 2 bytes are skipped).
