add http error pages (#381)

Browse Source 
* implement 404 for webserver - this is a quick hack, should be refactored later

* add http error pages ... design is more a placebo ;-)

* tune errorpages
fix some cgi related stuff, now only python is possible
executing and reading python file is possilbe, but it cannot receive any data from webui

* fix typo

* fix another typo
