Add tengo support to RemoteNickFormat (#793)
This commit add support for using the result of a tengo script in RemoteNickFormat using {TENGO} Also adds a new toml table [tengo] with key RemoteNickFormat and value location of the script. This also moves the TengoModifyMessage from [general] to Message in [tengo] Documentation: RemoteNickFormat allows you to specify the location of a tengo (https://github.com/d5/tengo/) script. The script will have the following global variables: to modify: result to read: channel, bridge, gateway, protocol, nick The result will be set in {TENGO} in the RemoteNickFormat key of every bridge where {TENGO} is specified The script is reloaded on every message, so you can modify the script on the fly. Example script can be found in https://github.com/42wim/matterbridge/tree/master/contrib/remotenickformat.tengo [tengo] RemoteNickFormat="remotenickformat.tengo"
