Mosh Support

[theftf]

Is your feature request related to a problem? Please describe.

mosh is very useful for a mobile shell access since it allows keeping sessions over a longs period of time and changing connections.

Describe the solution you'd like

it already was implemented in irssiconnectbot wich is relatet to termbot so it may be possible to backport the solution from there:
https://github.com/ddrown/irssiconnectbot/blob/master/src/org/woltage/irssiconnectbot/transport/Mosh.java
https://github.com/ddrown/irssiconnectbot/blob/master/src/org/woltage/irssiconnectbot/util/InstallMosh.java

Describe alternatives you've considered

if the backporting is not feasible it wold be necessary to re implement the feature.

We are currently not working on this. But I am open for pull requests to implement Mosh support.

+1 mosh is very useful because it removes typing delay
