first version to run web in subfolder
simplify code, use Ext.urlDecode instead of own code
rename kwc.urlPrefix to server.basePath

- because it's not only relevant for kwc
- basePath is also used by Zend_Controller
asseble urls thru router
add update script for converting web to support running in subfolder
session security for webs in subfolder
use BasePath validator only if basePath is used
remove automagic lastdomain file

instead server.domain is an always required setting now
todo: set that in setup
when installing set server.domain and server.baseUrl to current values
basePath -> baseUrl to be consistent with Zend_Controller
don't remove ending slash for home, Data_Home also doesn't do it
if baseUrl is not set (before setup) detect it automaticaly
simplify setup code: cut off baseUrl only once
don't detect baseUrl on cli
don't redirectToDomain in maintenance controllers plus assets

allows maintenance/setup being run without redirecting us away
Merge pull request #80 from nsams/run-in-subfolder
