projtool/usertool: default paging to off for most commands

For commands that are not expected to produce very much output
if any at all and do not require that the pager always be disabled
because they prompt for input, set the pager to off by default.

It can still be explicitly enabled for these commands, but
setting it off by default makes more sense especially for
commands that will be modifying settings and might return
a non-zero exit status that would otherwise be lost to
the pager.
