Fixed new forum permissions missing from IPB importers

[Jake Bunce]

These new permissions in XenForo 1.1 are missing from the vB importer:

View threads by others
View thread content

As a result they become "Not Set (No)" for imported groups which results in an unexpected lack of access for imported users.

Should have this fixed. Thanks.

Moving this back as it still applies to the IPB importer.
