Ctrl+a and ctrl+e shortcuts not fully working

[solusipse]

Sometimes when I use ctrl+a or ctrl+e shortcuts (move cursor to beginning and end of a line) finalterm starts to act unpredictably - cursor goes into insert mode, text partially disappears, sometimes I'm even unable to write anything else (have to ctrl+c). There is warning I get when it happens:

** (finalterm:4967): WARNING **: Unsupported control sequence: '\u001b[1@' (TERMINAL_STREAM_STREAM_ELEMENT_CONTROL_SEQUENCE_TYPE_INSERT_CHARACTERS)

This is another way ctrl+a breaks: type some 30-40 random characters with spaces in it. Press ctrl-a. It doesn't get back to the start of the line. It stops at a few characters from the beginning.
I'd paste here an example but it seems that copy and paste don't work yet. That's a show stopper but I'm reporting this bug anyway because finalterm has the potential to become my terminal of choice (when copy and paste will work).
Btw, I just installed from the ubuntu ppa. It would be nice if the About Final Term menu would report the git commit it was built from.

This bug is caused by some control sequences not being implemented and is thus a subset of #121.
