Unable to view styled report in Firefox 3

The constraint in Firefox is described here: http://kb.mozillazine.org/Security.fileuri.strict_origin_policy, and can be worked around by setting the preference security.fileuri.strict_origin_policy to 'False'.

However we are unlikely to get this setting changed in the Firefox package, so we will have to work around it. Workaround options are:

 a) use an embedded browser (webkit or gecko with this constraint disabled) to display the report
 b) dictate which browser (non-gecko based) is used to display the report, and add that as a dependency to the package(s)
 c) place a copy of the checkbox.xsl in the same directory as the submission.xml when the report is generated

Option c) seems the most sensible for now.

We could also use a remote XSL file, but that restricts functionality for offline users.

Fix commited for option c (copying xsl to same location as report) in trunk r483.

I have modified the code slightly to copy the stylesheet under the same directory as the report, instead of relying on the xsl_destination property to be set to the same directory as the filename property. Otherwise, it is not clear that both properties must always be set to the same directory.

Released in 0.7
