Optional and empty services

[vjrj]

Currently the dashboard only works when all queries returns values and all the ALA services are working as expected. This PR:

• Addresses partially Make panels configurable rather than deleting/commenting them out in code #96 making some services optional
• It also addresses partially Dashboard fails with a groovy error if the spatial server is down #85. This is also interesting in the LA community as it will allow to run the LA dashboard in new LA portals without data or LA portals without some services (like BIE, or spatial).

I've tested with:

• ALA services (double checking that I don't break nothing with this PR in the ALA production dashboard, attached my properties).
• An empty LA new deployment
• And now that I can generate inventories and /data directories easily, I also tested with Canadensys, Sweden and Vermont portals.

Bumping the ala-bootstrap3 plugin version is the main change I can see.

Tested locally again with ALA services, and works well to me.

@nickdos or @djtfmartin Can you have a look of this PR? I've tested a lot with different portals.
There are people in the community waiting for this. Thanks!

Thanks @djtfmartin!

It's possible to build this version as a snapshot in nexus?

Thanks again!

Ok, a new build of the dashboard is now nexus. Great, we'll use in short...
