[GAME] Add wildcard support for ent_remove_all command

[andris86]

Is your feature request related to a problem? Please describe.

Wildcard would be really useful if you needed to remove all entities belonging to specific group. If you wanted to remove all entities starting with npc you could use ent_remove_all npc* but this does not work, it returns that it can't find entity 'npc*'.

Describe the solution you'd like

Add wildcard support for ent_remove_all command.

Describe alternatives you've considered

Currently ent_fire command supports wildcards. By using ent_fire npc* kill I am able to remove all entities starting with npc. npc_destroy supports wildcards as well but is only limited to NPCs.
