First really changes

Began to write the new sql style

Deleted all files to keep a good overview, to provide a very good code
without confusions...
Finished the new SQL-Method

Finally I finished the new SQL-Method. There are no more ConVars used in
this version and it seems, that this buffer overflow gone too.

So here is a detailed list of the changes:
- added some code again from the removed files (mostly files like
propprotection.lua, antispam.lua), where not much changed
- changed the settings method nearly completely (no worries patcher, the
hardest parts are still the same than before and not recoded) ;)
- made a better overview in most of the files
- better performance!
- complete new antispamed-tools function
- fixed some bugs
and much more I can't remember.

So my next plans would be, to test this completely out, to see if there
is some error here and there, but normally everything should be ok now.
After that I would say, that we merge this branch to the general branch
and delte this branch.
Fixed Buddy System
Improved code by deleting tobool and tonumber

During the change of the sql settings, I found a problem, that every
setting-type is a string, if it is loaded from the sql table. Because of
that we also needed to convert every string to a number or a boolean.
e.g.: tobool( "1" ) = true or tonumber( "0" ) = 0

that needs much place and makes the code a bit confusing.
Now we only check the settings with REAL numbers, so we don't need the
tonumber() and tobool() in most cases anymore.
The only thing which i had to add is, that it converts the strings to
numbers, before it gets to the official sv_PProtect.Settings tables...
Final tests and fixes
