[Fix] Don't allow enter an instance while raid is in combat

[Tuxity]

No the function canplayerenter() is using before the teleport and canenter() is after the teleport

Now :

1. IsEncounterInProgress ? (Yes)

2. Can not enter in instance and display the message

canenter() it's like a security

Sorry, I missed second part.. Should work ok

Tuxity - this is patch for TBC core ?

[Tuxity]

No this patch it's for the master branch, but it's the same thing pour mangos-0.12 branch you can apply it manually if you want

This patch it's on my server 2 months and works fine (Maybe you need review some files for implement IsEncounterInProgress with SD2)

Update for last mangos-0.12 : https://gist.github.com/7e7026a5e7abf38f7a04

Add GM Check in CanEnter() function.

Tested & Work very well with 700 players since 2 months

This was fixed in [11783] by letting scripting library decide if an encounter is in progress in instances. Thanks nonetheless
