Cache collection metadata

[ansell]

The home page currently requests every collection's metadata every time it is rendered. It should have some form of caching to avoid this occurring:

specimenbrowser/grails-app/controllers/au/org/ala/specimenbrowser/ViewController.groovy

Line 17 in c30747d

def collectionMetadata = js.parseText(new URL(grailsApplication.config.collectory.servicesURL + "/collection/" + collection.uid).text)

@charvolant - this issue is sitting in QA, so has it been fixed in code somewhere? There are no commits recorded against it.

Looks like it is included in PR #15
