Decrease reliance on external E2 extensions

[Vurv78]

We need to decrease reliance on external extensions, to minimize pains caused by compiler / extension api changes and just have a more feature complete E2.

The most popular ones here should at least be addressed. I split the most significant and general ones that seem realistic to add to base E2.

Strike bonecore off the list. Posecore is partially implemented. Missing features as follows:

• All flex functions
• Eye functions
• Bone jiggle functions
• Bone scale functions
• Animtime

Also isn't Atmoscore outside of the scope of Wiremod as it's meant for an external addon?

[Hazeofdream]

Can the wire extras e2cores be made into the e2 base? not sure why they are separate. holoanim in particular is extremely useful

[Vurv78]

They are separate cause nobody has taken the time to port them.

In order to port them, first need to refactor the code (wire extras code is notoriously bad)

Propcore was originally in wire extras and was ported

[Hazeofdream]

holoanim should atleast pass that test as it's pretty basic.

possibly light as well

[Hazeofdream]

particleCore and it's variants are also pretty popular. This could be extended upon the existing effects core and is the most plausible one.
