Ignite function

[TheSilverDude]

This suggestion is simple:

Add an E2 function; the following one that is:

      e:ignite()

ignite(); when given an entity would be set to 0 by default; and if set to 1 would light the entity on fire. (I'd suggest not making this applicable to players; although I don't even know if it would be possible to use it)

Would be fitting with that new damage extension.
