Description of problem:
When launching a spice url from a browser link (such as spice://localhost:5901), browsers won't launch the virt viewer client. The spice protocol must be registered in Windows in order to do so.

Version-Release number of selected component (if applicable):
any

How reproducible:


Steps to Reproduce:
1. In your Windows browser URL window, type this and hit intro: spice://localhost:5901

Actual results:
The browser will either try to search for that url or say that there's not any program capable of handling that.

Expected results:
virt-viewer should be launched and open a connection against the supplied host

Additional info:
I think the windows installer should register the protocol. Here's a reg file that does it (note that the spice install folder is hardcoded):

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\spice]
@="URL:spice"
"URL Protocol"=""

[HKEY_CLASSES_ROOT\spice\DefaultIcon]
@="C:\\Program Files\\VirtViewer v5.0-256\\bin\\remote-viewer.exe,1"

[HKEY_CLASSES_ROOT\spice\Extensions]

[HKEY_CLASSES_ROOT\spice\shell]
@="open"

[HKEY_CLASSES_ROOT\spice\shell\open]


[HKEY_CLASSES_ROOT\spice\shell\open\command]
@="\"C:\\Program Files\\VirtViewer v5.0-256\\bin\\remote-viewer.exe\" \"%1\""
