Rearrange library order in configure.ac

[refi64]

Currently, autoconf checks for Boost.Filesystem before Boost.System. However, Boost.Filesystem depends on Boost.System, so the configuration exits with linker errors about lack of Boost.System symbols. Rearranging the order fixes that.

@kirbyfan64 - This github project is no longer maintained.
However, one of its forks at https://github.com/Secretchronicles/TSC is being very actively developed.
@Quintus has been leading the development on the fork.
Our team would be interested in working with you to get your changes into our fork, as long as we can port them and as long as they work with the game. We would need to determine whether this should go into the next release (not a new feature that's likely to break other code) or in a future release (development).
I've also been using @ on your name to include you on some discussions. We would love to have more team members.

@kirbyfan64 Yes, this repository is basically dead. Please join us over here. But please note we do not use autotools anymore for building, but cmake.

Vale,
Quintus
