git: update to ignore .deps and protobuf .cc
Merge remote-tracking branch 'vyrly/master'
Revert "fixed bugs that ft found" wrongly merged?

This reverts commit f18aface6b3366f1550f39448a0fb56fbac1cfee.

It seemed to be wrongly marged.
fc678d09e659b358 removed consts at line 260 in OTCrypto.cpp
f18aface was adding them back, despite being month older, seem
to be applied in my tree by my mistake.
