ApplyCommand: use context lines to determine hunk location

If a hunk does not apply at the position stated in the hunk header
try to determine its position using the old lines (context and
deleted lines).

This is still a far cry from a full git apply: it doesn't do binary
patches, it doesn't handle git's whitespace options, and it's perhaps
not the fastest on big patches. C git hashes the lines and uses these
hashes to speed up matching hunks (and to do its whitespace magic).
