move Lacuna.Panel into standalone Panel class
game->menu can be a normal dependency
all files which call require([]) now list it as a dependency
save rpc data result.empire,result.body under result.status for consistency for other code
handle browser page-refresh

* keep login session ID in session cookie
* if session cookie exists, don't require login
clear user data / buildings on logout
consistent capitalization to enable searching
get rid of illegal trailing commas
silence 'seconds' var masking 'seconds' argument warning
remove unused variable
circular dependencies

between lacuna <> empire < login <> lacuna.
between lacuna <> body.
always use require("") to access other modules within a circle.
add 'require' dependancy to empire & login
...and mapStars is also in the circular entanglement
use a variable instead of literal CDN URLs
fix asset URLs
Another try to sort out github wiki formatting
Moved some calls to use named arguments
Updated README to show actual error message
