Fix compiler error in g++ (GCC) 4.7.0

Compiler error was due to variable redeclaration (variable inside of for
loop had the same name as the loop iterator variabele) - fixed through
renaming of the inner variable.

Added debugging mode to the protocol

Allows inspection of message data. It is off by default since it consumes
additional bandwidth, but it can be turned on using the net_debugMode option
in manaserv.xml.

Currently the option only affects outgoing data for each host individually.
In particular, enabling this debug mode for the server does not automatically
make the client annotate its messages.

Small GCC 4.7 compile fix

Not entirely according to the standards since this is a C99 header,
but that's better than not having it compile at all, or switching
it entirely over to C++11 mode just now.
Fixed type of returned value from MapReader::readMap

GCC 4.7 warns about this, yay.

Don't send NPC text as fixed-length string

This is intended to be used only when the string length is known. The
client was deriving the length from the remaining amount of data in the
message, but that doesn't work in the new 'debug mode' of the protocol.

Fixed handling of skills

 - Removed possibility of skills getting mixed with attributes
 - Made the server sending the level of the current skill on exp change
   (currently the client could calculate it itself, but it allows more
    flexibillity in future this way)
 - Fixed reading of skills out of the database
   (for some reason the status effects were added as skills)

** Needs clientside patch as well (coming soon) **

Fixed the get_beings_in_rectangle function.

Previously it only used the rectangle iterator which in fact iterated over the
beings in the map zones and returned often way higher number of beings compared
to the actual rectangle.

Change is tested.

Added lua binds for issuing request of quest variable + bind for trying to read them

The difference to the old chr_get_quest bind is that this allows querying quest
vars from non npc functions as well.

Change is tested.
