Message:

Make variable getters return NULL instead of "<null>"

This fixes trac-#184:
Since commit 010a9511420887329269aa51e7598533e826c57f, the default zsigs
show up as empty; BarnOwl::default_zephyr_signature() checks
BarnOwl::getvar('zsigproc') as a boolean (which may be incorrect if you
happen to have a zsigproc called 0). As of that commit, BarnOwl::getvar
returns "<null>" instead of undef.
