Disabled the caching in iu._listdir, because it prevents applications that generate and reimport
plugins from working.  The cache does not have the newly generated plugin, and therefore any attempt
to import that plugin fail.  So, we must just list the directory every time instead of trying to use
a possibly-stale cache.
Added hooks and buildtests for wx.lib.pubsub.
Added a test case to demonstrate the problem that is fixed by disabling the _listdir cache.
Used a more esoteric name for the attribute added to sys that does the detection of which
protocol we are using with wx.lib.pubsub.
* removed spec files for the test_wx_pubsub* cases; they are now listed under NO_SPEC in runtests.py.
* added license headers to all new files in "hooks" dir.
* for protocol detection, a module variable is now set in PyInstaller.hooks.hookutils instead of sys.
* removed bare print; logging mechanism used now.
* the test_wx_pubsub* cases are now skipped if wx is not installed.
* removed printouts from test files upon success.
