Updating devel/bullet

[Gergely CZUCZY]

Hello,

Could you please update the devel/bullet port to 1.82 (latest as of
now)?

I've tried to do it myself, however some files didn't get installed as
i've noticed when doing the make package.

The changes I've noticed so far:
  1) The release tarball has the revision number, so does the workdir,
  therefore WRKSRC has to be adjusted accordingly
  2) the LICENSE file seemingly got renamed to BulletLicense.txt
  3) files/patch-src_BulletSoftBody_btSoftBodyInternals.h is obsolate,
  the source has this now.

Also, if you can, some options to disable example building/installation
would be nice.

Thanks in advance.

Regards,
Gergely
