$(ccuNotReady) shown in Webinterface during startup

[jens-maus]

Starting with 2.25.15.20170114 (beta4) of RaspberryMatic untranslated messages are shown if the Webinterface is accessed to early or if ReGaHss crashes and is thus unreachable. The messages shows $(ccuNotReady) instead of showing a translated/localized message for the user.

After analysing the problem, the issue seems to be related to the /www/error/error-503.html file being used to display the error page and which contains incorrect javascript locations compare to the error-500.html file that was used in previous releases of RaspberryMatic.
