Update README
Updated Readme

Took the opportunity to add some information on the
telnet server and online gaming.
Fix: Command-line arguments incorrectly handled

* Traceback generator always tried to write tb -> double fail on Exception.
* Config file was not parsed
Added primitive "sight range" calculations to Map

NPCs are only drawn if they are in sight, dungeon and
item piles are highlighted if in sight.
Added MapOverview-view

Navigate over a fullscreen version of the map.
Inventory-view automaticaly uses player's inventory now

Before, it was necessary to manualy pass the inventory to
view when activating the view, which is completely stupid.
Added wielder-information to wieldable items

Wieldable items now know who wields them, changing the on_wield_attack
method. It also serves as information for manipulating code, so they know
for sure that the Item is in use.
Fixed not-round view highlighting

The view hightlight range was truncated by to small iteration ranges.
Dungeon "fog of war"-display

Display only parts of the map that were visited by the player before.
Started .gitignore

Ignore python-cache and tty-records
Added sophisticated (but slow…), occluding visibility calculations

Visiblility is now calculated by raytracing from the center to the edge
of a circle. The calculations were speeded up by using generators where
possible, but the delay introduced is noticable on autorepeat in open
spaces. Further improvements are required.
Fixed incorrect handling of extra config and added sectio-whiteliste

We only want the user to configure specific, whitelisted sections, e.g
the keymapping and *not* in-depth game related aspects.

Also the extra config was added after some internal structures like
the keymapping were initialized, rendering the changes useless.
Visibility test performance increased

Only calculate visibility field once per update-draw cycle.

It seems that the game performs better in the MapOverview than in Play
view, which is quite odd...
Changes required for python2 downgrade
Python2 comp.: Exception as -> Exception,
Added python2 notice to README
.gitignore compiled python files (pyc)
Basic color support

Added colors definitions in config file and a method in Game
to initialize the color system of curse.

The Map class was modified to display color, but it is slow as FUCK!
