plugin: roles missing after switch_to/restore blog

[MrMaz]

AFAIK this only applies to the plugin version.

Since switch_to_blog() reloads user roles to match the new blog id, and reverts them on restore_current_blog(), the special bbPress role masks are not re-applied.

I fixed this in my app by running bbp_global_access_role_mask() manually, although I'm not sure if there are other role setup items that should be run as well.

It might be a good idea to hook the role mask functionality into 'switch_blog' in addition to the initialization routine.

Most likely related to #1693.

(In [3689]) Move 'bbp_setup_current_user' action off of 'bbp_init' and onto 'set_current_user.' See #1722.

r3689 fixes one part of the problem. The other is definitely part of #1693. Closing this one as fixed as it handles bbp_global_access_role_mask() specifically.
