* Makes the spelling of 'mjollnir' consistant and renames singularityhammer.dm to wizard_weapons.dm 2 (#79700)
## About The Pull Request
All the below copied from #79588
Does as the tin says and renames all instances of 'mjolnir' to
'mjollnir' . They are TECHNICALLY both correct but because 'mjolnir' was
only used for the spelling in game for the hammer itself and the icon
when worn on the back I decided on two l's. This also means I had to
change the icon name for the back sprite
If I'm missing any files with it spelt 'mjolnir' please tell me
While I was at it i also decided to change singularityhammer.dm to
wizard_weapons.dm because apparently the file is supposed to be where
wizard weapon are stored and having it be named after a single weapon is
confusing incase people add more weapons later on.
## Why It's Good For The Game
More consistent spelling.
Code wise it makes it more clear what the intended use for a file is
## Changelog
