switch .profile and .bashrc contents

Put aliases in .bashrc, instead of .profile, like they're supposed to
be (so picked up by sub-shells). .bashrc now reads a .bashrc.local for
local customizations.
HPIB fast binary mode now uses the PRU

The last part of the app to be switched to using the PRU to access the
5370 was the HPIB fast binary mode code. There is a separate PRU code
command PRU_TI_MEAS for taking a TI measurement as fast as possible via
chained register access.

add support for store/recall of key settings

Runtime argument "-rcl|-recall [profile_name]" and commands "rcl|recall
[profile_name]" and "sto|store [profile_name]" to manage
saving of key settings. A key is considered "pushed" if the
corresponding LED is lit. The current key state is saved into the file
~/.5370.[profile_name].conf every 5 seconds or so. Thanks to John Miles
for suggesting this feature.

better way to solve this problem?
