EVEN FROM THE GRAVE I WILL NOT STOP TAMPERING WITH RANGER (also bugfixes)

[IjonTichy]

Things that changed:

• String comparison bugfixes (switch to strcmp instead of ==)
• Widescreen Mjolnir sprites + no more black pixels on said sprites
• Mjolnir, if you survive an underwater whack, continues the swing animation rather than going straight back to Ready
• QRL dropped down to 5 rockets on pickup
• Grenades and rockets do 5 more damage in coop, so demons no longer survive rockets with 1 HP
• samsara_pistolammo has the QSG only use shells every other shot
• Quake 1 megahealth sound
• Removed packagepk3.py for being deadweight
• ConsoleCommand("nextmap") -> Exit_Normal(0)
• Added Caleb
