MySensors 2.1.1 release (#752)

* Bump version to 2.2.0-beta (#713)

* OTA: Add incoming FW block check (#718)

* Linux: Add support for SPIDEV (#734)

RPi and Linux refactor.

Add GPIO Sysfs for GPIO operations.

Update configure script.

Fix some cppcheck warnings.

Add serial emulation that prints to stdout.

Fix some file headers.

* Fix getControllerConfig() (#737)

* Rename MyHwATmega328 to MyHwAVR (#738)

* AVR: Restrict fast pin function use (#739)

* Fix signing presentation bug (#740)

* Consolidate open PRs for bugfix release (#741)

* Revert "Bump version to 2.2.0-beta" (#744)

* Merge Master into Dev (#745)

* Fix spi flash error when compiling in Arduino IDE 1.6.6

* Bump minor version

* Fixed "invalid suffix on literal" warning

* Fix addressing bug in _doSign bitfield

* Make sure nodes not supporting signing informs GW

A node that does not support signing, still needs to inform the
gateway about this to make sure the gateway carries a valid signing
requirement table when a node Id that was requiering signing stops
doing this.
This fixes #286.

* Prevent SecureActuator from accepting ACKs as commands

As ACKs are not currently signed, allowing ACKs as commands
is a considerable security hole for this sketch. This is now resolved.

* Backport of bugfix (#259) in repeaters when forwarding signed messages

* Bumped version to 1.5.2

* Corrected doSign variable name (was _doSign)

* Bumped version to 1.5.3

* Add NULL termination to payloads

Messages addressed to "this" node, will have a null char
appended to the payload after message verification is
done, because some "getters" assume the message being a
string.

* MySensors 2.1.1 release
