Release v1.2.0

This release includes code improvements and some new features:

• Implemented the -i flag for generating default bots.yaml file
• Implemented support for setting config options in the bots.yaml file (flags will override them)
• Configured the webserver to use the network IP for the strict mode instead of headers (safer, doesn't work behind proxies (yet))

Note: the checksums are generated from the executables, not the archives.
