Add new skin flag SF_NOSHIELDABILITY

This adds the skin flag SF_NOSHIELDABILITY, an easy way of disabling shield abilities for custom characters. The main difference between this flag and just returning true in ShieldSpecial is that this prevents target arrows from appearing with the attraction shield.

Also allows ShieldSpecial to access the whirlwind emergency jump so it's less of a pain to override that by itself.

Based idea. You have merge conflicts though! D:

love when a blank line causes a merge conflict

fixed now

added Feature label

A GETFLAG macro for the new skin flag needs to be added, at around https://git.do.srb2.org/STJr/SRB2/blob/next/src/r_skins.c#L496

Otherwise it would be impossible to set it using noshieldability = 1 for example

What's the limit on the amount of character flags we could have, if there's one?

Since it is a 32-bit number, 12 left after this merged.

could we eventually make it 64-bit if we bloat it enough??

:VVv
