Code to alter/check feature properties in Lua.

This commit moves str_to_fprop from initfile.cc to fprop.cc. It also
introduces two new dungeon Lua wrappers: fprop_changed(x, y, fprop),
and fprop_at(x, y, fprop).

fprop_at(x, y, fprop) will return testbits(coord_def(x, y), fprop).

fprop_changed will either add the fprop to that location, or if it
already exists there, it will remove it from that location. It will
returrn a boolean value of true if it altered the location, and false if
it did nothing.
