During extended uptime of DreamDaemon, $HOME/.byond/cache will fill up with lots of files. Given enough time, there will be hundreds of thousands of files in the cache directory.

There are a couple things I'd like to suggest:

1. Cleanup of cache items that are no longer needed.

2. Extend the cache directory structure, eg:

$HOME/.byond/cache/1/1/11C8C4F8 vs $HOME/.byond/cache/11C8C4F8
$HOME/.byond/cache/7/D/7D7FF906 vs $HOME/.byond/cache/7D7FF906

This solves cleanup issues where there are far too many files to effectively clean up this directory manually (gotta love rm complaining about too many arguments).

3. Add a DreamDaemon option (or env variable) that allows setting of a custom cache directory instead of using $HOME/.byond/cache.

(are there collision issues when two servers are actively using the same cache directory? I don't know -- I started giving my servers a custom $HOME to make it easier to handle)
