Title: Add external links to choices fields

You can now use the "clickURL" key in a choices field definition to
generate an info button to provide more information.

A sample field definition is below:

```xml

class
OTMChoicesDetailCellRenderer
fname
pests
clickURL
http://www.forestry.gov.uk/pestsanddiseases
key
tree.pests
label
Pests
minimumToEdit
0

```
