Add edit window for typeflags (ActorFlags)

[thekovic]

Is your feature request related to a problem? Please describe.
Currently, typeflags don't have a nice edit window which means the flags must be researched and edited manually. This is unfortunate as these flags can be quite useful (especially the 0x100000 flag which can be changed to, for example, achieve killable wolves/jaguars).

Describe the solution you'd like
Add edit window for typeflags (documented as ActorFlags similar to how thingflags are editable.

I think it'd be wise to also make typeflags editor for other types: explosion-flags, weapon-flags, particle-flags and item-flags.
Also flag editor for physics-flags would be great to have.

The new flag editors should also include flag names for JKDF2 & MOTS games and display them according to the current project type. https://www.massassi.net/jkspecs.

Note that the typeflags should be interpreted based on the thing type.
e.g.:

if thing.type = 'actor' then `FlagEdit.EditActorFlags(f)
if thing.type = 'explosion' then `FlagEdit.EditExplosionFlags(f)
if thing.type = 'item' then `FlagEdit.EditItemFlags(f)
if thing.type = 'particle' then `FlagEdit.EditParticleFlags(f)
if thing.type = 'weapon' then `FlagEdit.EditWeaponFlags(f)
