(Closes issue #170) : Enhancement: Provide a command to create new project by copying it from an existing project

This is a bigger change:
* only use one instance of CUrlInfos
* pass around that one instance to wherever it's needed
* guard the data in CUrlInfos with critical sections
* make sure the data is guarded only for short times
* in the monitoring thread, use a copy of the CUrlInfos data because of the point above

* enable all controls in the url dialog
* don't check the url in the url dialog but do that later (not implemented yet) in the main dialog or even the check thread
* add load/save methods for our persistent data

* the url dialog only needs one CUrlInfo, not the CUrlInfos object
* use a map with the URLs as a key for the CUrlInfos instead of a vector
