cmd_terminate() is failing to release all memory allocated by the CLI code

[rwestphal]

This is not exactly a memory leak but releasing all memory explicitly on exit is always a good idea.

have a branch with a working uninstall_element on my laptop, that should fix a lot of this

[eqvinox]

should be fixed by #139

#139 merged, closing (zebra did not leak any CLI-related memory in my tests)
