Primarily aimed at reducing the size of the old 'man' (now: files) table, using smaller integers to refer to man contents and text fields, and storing a shorthash as an integer for quick lookups. This better normalization also removes the need to keep a separate 'man_index' cache for the search function. The old schema wasn't necessarily bad, but I was in the mood for some optimizations. And a little cleanup. Prolly introduces a bunch of new bugs, I haven't tested this too well.
