Actually almost all fTools algoritms already available via Processing,
only few are
"missed". This "missed" algs now also ported, but not commited into
master because
of feature freeze.

Just remebered that some fTools algorithms were ported to C++ by Carson Farmer
(original fTools author) several years ago. One can find this
algorithms in QGIS analysis
library, look at QgsOverlayAnalyzer [0] and QgsGeometryAnalyzer [1].
Maybe it is better
to update this code instead of writing new one.

As I said, almost all fTools functionality already available and
missed algorithms
are ready to merge.

Regarding fTools (and maybe GDAL Tools) removal, I think we need to wait until
Processing can completely replace this plugins.
