Add startup.lua module with startup.ensure(), wait() functions.

This lets a calling script verify that it's running at the right point in the
viewer's life cycle. A script that wants to interact with the SL agent
wouldn't work if run from the viewer's command line -- unless it calls
startup.wait("STATE_STARTED"), which pauses until login is complete.

Modify test_luafloater_demo.lua and test_luafloater_gesture_list.lua to find
their respective floater XUI files in the same directory as themselves.
Make them both capture the reqid returned by the "showLuaFloater" operation,
and filter for events bearing the same reqid. This paves the way for a given
script to display more than one floater concurrently.

Make test_luafloater_demo.lua (which does not require in-world resources) wait
until 'STATE_LOGIN_WAIT', the point at which the viewer has presented the
login screen.

Make test_luafloater_gesture_list.lua (which interacts with the agent) wait
until 'STATE_STARTED', the point at which the viewer is fully in world.

Either or both can now be launched from the viewer's command line.
