Restore ttf-thai-tlwg package accidentally deleted in r243506

Per sbc@, it's possible that this package no longer exists in saucy. If so, we need to figure out where the fonts went and make sure the code checks in content_shell work properly . Perhaps this just needs to be a conditional install.

However, the package is still needed on Precise, so restore it for now.
