No Ethereal Surge on Mages (#10121)

* problem location identified (breaks code)

* problem identification notes

* Add class checking to ES (does not yet notify user)

* Add error message

* Add .gitattributes

Attempting to fix line ending disaster

* package stuff

so I can see what's broken

* add reminder and hopefully fix gitattributes

* Fix lint errors

* Redo surge fail notifs

* exterminate rogue comment, fix gitattributes

* Remove unused import 

As per @paglias' request.

* fix(lint): remove extraneous expression

* Delete .gitattributes

* Fix skill key surge -> mpheal

* Show notification only when there are mages in party

* Fix notification being too big and appearing outside the notification div

* Remove unused code

* Only show the notification on parties with 2 or more mages

The caster is a mage, so certainly at least 1 mage will be counted.

* Automated test: mpheal does not heal other mages

* Fix lint error

* Fix typo in test description

* Increase performance of test

* Using target instead of requestion partyMembers again

* Rename variable 'party' to 'partyMembers'

* Update strings in English

* spell -> Skill
