Mostly bugfixes and small changes.

- Changed the number of times a creature can appear in an outdoor encounter to match the documentation.
- Moved count_monst to cCurTown::countMonsters.
- Code cleanup in create_wand_monst() - removing unnecessary comparisons with true or false.
- Moved is_null_out_wand_entry to cOutdoors::cWandering::isNull().
- Moved is_null_wand_entry to cTown::cWandering::isNull().
- In create_wand_monst for the town case, I changed it so that the fourth monster (and only the fourth monster) has a 50% chance of appearing twice.
- In monst_check_speciall_terrain, replaced the commented check for town number in the force barrier case with a check for a new bit field variable: univ.town->strong_barrier
- Removed specials1, specials2, res1, and res2 from the townrecord; the checks for specials2 & 1 have been replaced with checks for the new bit field variable defy_mapping.
- In adj_town_look(), the lines uncommented in the previous revision were reduced to a single add_string_to_buf() call.
- Removed the 50 node limit in favour of an interrupt key. Pressing command-period while a node sequence is underway will now interrupt it. Control-C is supposed to have the same effect, but it's not working yet.
- Affect PC nodes other than Kill/Raise Dead now only affect the active character when the party is split up.
- Added missing breaks in the split party node which would allow the party to be split in combat or when already split, despite a message saying they can't.
- Added a second operator[] to cCurOut which takes a location as a parameter rather than an x coordinate.
- Properly fixed an earlier error in cPitc::init() which had a temporary fix; it turned out to be a case of static objects not being initialized in the right order.
