Allow fingerterm to use installed vkds and swap them
I have 3 virtual keyboards installed on my Jolla. I find I am not able to use them in fingerterm. This causes me problems when trying to deal with non-English files and directories. I recieve files with different language names and I ssh to servers. For example I often ssh to servers with Japanese locale and Japanese directory names. I have no means of switching keyboard in fingerterm to easily type directory names. I would expect the same issue with Chinese users or many many other languages. Would be nice to change various keyboards in fingerterm like the rest of the OS.
