a7d006b637 Rewrote timer code. 
The new code is based on timestamps, rather than delays. This eliminates the
need to update every timer in timer_process(), which cost a non-trivial amount
of CPU time on low-end machines.

This involved changes to every user of the timer code, so this change almost
certainly introduces bugs.

d5b7a69ff6 Respect the WX_CONFIG_PATH variable 
The configure script takes a --with-wx-config argument, we should respect it.
It is very necessary for FreeBSD, which installs wx configs under more specific names such as 'wxgtk2u-3.0-config'.
