Apply webstart patch to insight

[jamoore]

A patch was provided by Mark Woodbridge for enabling Webstart in Insight. Having it in place is a good first step towards getting webstart working for everyone:

We talked about Web Start in Paris. I've attached the stuff necessary to get it working. It's a bit fiddly.

The patches are against shoola tag Beta-4.1.1. The importer didn't need patching.

1. Apply patches
2. Build insight and importer
3. Run webstart.sh, which creates /tmp/omero
4. Sign the jars
5. Copy /tmp/omero to web root

Notes:

- The jnlp files are jsp files so that the codebase and href attributes don't need to be hard-coded. I'm not sure whether this necessary but I must have done it for a reason
- The <jar> entries in the jnlp files are hard-coded and were generated using the 'find' statement that is commented-out in webstart.sh
- You need to use a proper (i.e. not self-signed) certificate if you don't want users to be given lots of warnings
- The Config.java hack shouldn't be necessary but I needed to do it to dynamically find where the config files are
- It's possible that I missed some direct File loading calls but no-one has complained yet
- The readConfigFile method is written so that the clients don't have to be web started but if all resources were loaded using a class loader (rather than using a FileInputStream) this wouldn't be necessary

Let me know if you have any questions. I sent this stuff to Brian a while back - not sure if he made any progress. I'm sure it can be simplified.
