[Rachana] "Ignore Combining Marks" for psts rule
Harfbuzz (and Uniscribe) reorders dotreph to the end of cluster (REPH_POS_AFTER_MAIN).
This causes ligatures involving post base Matras (eg:  ൎത്തൂ) to detach from the conjunct.
Fix this by marking "psts" lookup to ignore above-marks (Ignore Combining Marks in fontforge)
See discussion http://lists.freedesktop.org/archives/harfbuzz/2013-October/003734.html

Test cases:  ൎത്തൂ, ൎക്കു, ൎച്ച്
