move Com_Filter (and its Com_StringContains) from common.c to q_shared.c, to enable the game to use wildcard filtering for commands, that is consistent to the one used in cvarlist
let the entity system make a big step torwards OOP, by embracing entityClasses
let Com_Filter take const arguments
Merge branch 'master' into entities
make /entitiesList searchable by classname and all names/aliases  and display additional aliases if available
add origin information to /entitiesList and format the whole thing a little bit better, hopefully fixing the unintended newline via rcon
