[sakai2-tcc] Proposal: Switch to Tomcat 7 for Sakai 2.9

[Steve Swinsburg]

Looks like the JSF tool issue is resolved.

Adding commons-el to shared makes these tools render just fine in Tomcat 7.

cheers,
Steve

Is this anything like other projects where one version is considered more stable than others (at least as far as production is concerned) and others are have more experimental features in them? Usually when something is under active development, it's not necessarily a good thing and taking the version (-1) that's been run for awhile might work out better or at least be easier to justify to an operations team.

I know we're going to have to do some library upgrades and significant testing either way. It's probably not worth doubling up on the effort if a case can be made to just go straight to 7.

Someone that knows something about JSF will need to take a look. Samigo also fails but its stacktrace is more promising which hopefully means it can be resolved. This could be the first to be fixed so we know where the issue is with the others, perhaps.
