more efficient changelog reading for recent changes

getRecents now reads the changelog backwards in 4KB chunks instead of
loading the whole file into an array and rsort it. This should be more
memory efficient (and probably faster) for large change logs.

Note: the format of the array returned by getRecents changed slightly
      plugins relying on it need to be adjusted. Sorry.
