Previously the index.jsp of the ROOT web application was storing
PKI UI main page which contains links to PKI subsystems installed
on the instance.

Now the file has been changed to redirect to /pki which provides
a new PKI UI welcome page. The PKI UI main page itself has been
moved to /pki/ui.

Ticket #1523

Move the dire warning about the crypto object to sections where it applies.

Also slightly changed the message due to context.

Provide simple textual warning when the user is using a browser that no longer supports the crypto object, which results in reduced CA certficat enrollment functionality. For simplicity provide the warning at the top of the main index page and at the top of the CA's services page. The services page is where the pkispawn of the CA points the uers after installation. The ticket originally called for a JS warnign but the simple text warning should be less intrusive and repetitive to the user.

Ticket #1398 Provide UI Javascript warning for missing Mozilla Crypto Object in the CA.

The ROOT's index.jsp has been modified to show the links to all
subsystems installed on the instance. When opened, it will show
the services provided by the subsystem.

The pkispawn output has been modified to show the subsystem URL
more consistently:
   https://<hostname>:<port>/<subsystem>

In all subsystems except TPS the page will redirect to:
   https://<hostname>:<port>/<subsystem>/services

The ROOT's index.jsp has been modified to check each subsystem's
servlet context for null before accessing the value.
