gateone.js:  NEW FEATURE:  `GateOne.Base.superSandbox()`.  It's an alternative way to wrap JavaScript in a sandbox that automatically takes care of loading dependencies before loading the code wrapped in the superSandbox.  All of Gate One's JS code (for the most part) has been modified to use the new superSandbox and the result is spectacular!  Pages load *much* faster now and the responsiveness overall is improved (seriously!).
go_async.py:  Changed the order in which some `__init__()` stuff is loaded in order to resolve a problem reported in issue #303 (https://github.com/liftoff/GateOne/issues/303) where you'd get an AttributeError exception if the `MultiprocessRunner` had it's `__del__()` function called before it had a chance to complete instantiation.
gateone.py:  You can now disable the cleanup of user's 'logs' directories entirely by setting "user_logs_max_age" to "0".
gateone.py:  Changed how the license information is set.  Gate One will now default to "AGPLv3" as the __license__ but will override that value at startup if a .license file can be found.  Also made it so that the license information is sent as an HTTP header ("License") for all requests.  This is to easily distinguish between commercial licensees and open source users.
utils.py:  Added "y" (years) support to the `convert_to_timedelta()` function.  It doesn't take leap years into account but whatever.  It's good enough for Gate One's purposes.
app_terminal.py:  Removed the legacy "session_logs_max_age" option from the auto-generated 50terminal.conf as it isn't used anymore.  The correct setting for that is "session_logs_max_age" which is in 10server.conf (under "gateone").
Example Plugin:  The Example plugin's JavaScript has been modified from `GateOne.Example` to `GateOne.Terminal.Example` to better reflect what it belongs to.
Everywhere:  All JavaScript has been updated to use the new `GateOne.Base.superSandbox()` sandboxing mechanism.  This allowed me to reduce the timeouts on `GateOne.Utils.runPostInit()` so everything loads much quicker now.
termio.py:  Changed the `RE_OPT_SSH_SEQ` stuff to match the new style of setting the SSH connect string inside of ssh_connect.py.
Logging plugin:  Increased the size of the pagination text.
Logging plugin:  Fixed a bug where the 'printable' (aka 'flat') log output wasn't showing the background color the entire length of the page.
