while doing a final pass on the testing, we discovered some issues. These are all resolved in the PR.

Mostly, main.go in siad got rehashed to be more friendly to the user, trying first to find a 'style' folder in the current directory, and then looking in the config file. The code was also cleaned up quite a bit.

Some extra error information got added to siacore to help with debugging.

The renter constants got changed to be shorter - files are only uploaded for 3 days or so.
