[PATCH] lisp/org-collector.el: Add support for TBLFM

[Slava Barinov <rayslava@gmail.com>]

The :tblfm keyword adds formulas to the end of table so they are applied right
after collection is done and the table is generated.

* lisp/org-collector.el (org-dblock-write:propview): Add support for the
:tblfm keyword.
