Make sure all command functions return True
Because recent adjustments to handler_active() rely on the
call_handler_function() return value to determine whether something
went wrong, we need command functions to return something which
evaluates boolean True if they ran to completion and didn't raise an
exception. Just return True from all of them for now, but they may
see more dynamic result handling in the future.

Increase timer resolution in test config
Significantly speed up the timer in the test config (by a factor of
1000). On fast machines with cached tox envs, this results in an
order of magnitude improvement in test runtime. Related timer values
are lengthened to avoid test failures due to timeouts, and some
others are shortened for consistency.
This is obviously not suitable for normal operation, so the sample
configuration remains untouched and thus the tox selftest_config
testenv does not benefit from it.

Use call_hook_function() in handler_active()

Preserve loglines on reload
When a reload occurs, prepend the new universe's loglines with those
from the old universe so they are not lost. This may temporarily
bloat the loglines list slightly over the limit, but it will be
adjusted downward the next time anything new gets logged. Also
adjust the `show log` selftests to handle linewraps in a new place
when the total loglines count is higher.

Tighten up eval() scope in show result subcommand

with the `show result` administrative subcommand, replace its eval()
invocation's globals with just the mudpy module namespace and the

any attempts to access other globals and locals within the
command.show() function's scope raise an exception.

dynamic routine on Python 3.7 and later, which will use all *.py
files in the top level of the package so none are forgotten in the
future. Keep a hard-coded fallback list for support of earlier
Python versions, but compare the two so this list is guaranteed
complete for as long as it is maintained.
