see Changes

- fix weight update on insert-merge
- refactor get_split_ob into ->split, taking advantage
  (partially only) of split managing client updates.

*** empty log message ***

increase jumping max to 3 spaces or the skill level, whatever is lower. this is actualy not bad, it quadruples your potential running speed...

*** empty log message ***

- new type: INSCRIBABLE
- inscription only works on inscribable items (spellscrolls special cased)
- add new empty scroll, empty book and empty mailscroll archetypes
- use mailscroll in ipo.

- upgrade crossfire trt to the GPL version 3 (hopefully correctly).
- add a single file covered by the GNU Affero General Public License
  (which is not yet released, so I used the current draft, which is
  legally a bit wavy, but its likely better than nothing as it expresses
  direct intent by the authors, and we can upgrade as soon as it has been
  released).
  * this should ensure availability of source code for the server at least
    and hopefully also archetypes and maps even when modified versions
    are not being distributed, in accordance of section 13 of the agplv3.

update copyrights in server/*.C

rebalance singing and oratory, copy_doc

remove superfluous/broken settings and related code

- COZY_SERVER:
  enabled most msall adjustments, changed digestion formula to the original one,
  party member treament w.r.t. pets enforced.
- PROHIBIT_PLAYERKILL: default
- real_wiz: removed and enforced
- create_home_portals: removed and enforced
- casting_time: removed and forced to be off (was crashing anyways)
- was_wiz flag removed and treated as off usually unless it was used
  in place of flag_wiz.
- do not save or restore wiz, wizcast and wizpass flags.

do not output archetypes with names starting with type_ or class_, a bit of a hack

This is the first rough cut of the skill use system (use the STABLE tag).

Details will likely change, and combat skills do not work very well, but
it works quite well.

Players no longer have a shoottype or range slots, instead, each player
has these members:

   combat_skill/combat_ob  the currently selected skill (and weapon)
                           for direct attacks.
   ranged_skill/ranged_ob  the currently selected ranged skill (and
                           bow/spell/item)
   golem                   the currently-controlled golem, if any.

rework material code in preparation for nuking object->materials, also add some useful object methods in preparation of the mapspace limiting

- fix a crashing bug inside the random map generator
- do not decrease dungeon size with random map depth

more preperations for player eviction

- added maptile->insert and object->insert_at methods that might
  make code using it clearer.
- replaced some insert_ob_in_map calls.

- preliminary check in, stuff is rudimentarily working
- moved most of the player creation process into a perl coroutine
- changed internal design of player management to not reuse
  and morph the object in funny ways. should be safer and much
  nicer to handle.
- got rid of some annoying hacks, such as clear()
  (TODO: get rid of player_pod and other stuff now unnecessary?)

- minor cleanups
- minor optimisations (in_player vs. is_player_inv)
- added P_PLAYER map flag
- some (dead) concept code

added a needed abstraction

replace some function- by method-calls

replace was_destroyed by much simpler and less expensive ->destroyed,
which is valid, as objetc pointers are now reliable.

expand initial tabs to spaces

further refinements

fixed a possible crashbug with sining...
