[ft2900] Fix issues entering channels via UI   #2385
This patch fixes problems when entering memories to the FT-2900
via the CHIRP UI.  The set_memory function was leaving "unknown"
areas of the memory unset, which caused intermittent problems,
depending on what had been in those fields before.  Fix is to
initialize all unknown fields to 0, mimicing what the radio would
do if creating new channel via the radio's front panel.  Also,
we re-order the power levels to make the default "Hi", again
to mimic the radio's front panel behavior.
