aquila-gateway - Released version 0.6.0

- Implemented removing devices from the monitor API.

- Changed Monitor API: All "*/get" command topics are now "*/req" for consistency with responses ("*/res"). Old API is still supported but deprecated.

- Minor bug fix: incorrect buffer function usage in Serial and TCP Transports.

The first change is useful when managing devices from a custom app. Usage:

Removing a device:

1. subscribe to gw/devices/remove/res
2. publish to gw/devices/remove/req a json with the address or id of the device to delete. Example: { "address": 23 } or { "id": 23 }.
3. You should get a JSON response via the subscription to gw/devices/remove/res: { "success": true } (or false).
