Provide options to autoexpand templates and collections on report page.

Documentation for changing the default behavior on the report page. Without modifying the properties the report page should behave as it did before: collections are automatically expanded, templates are automatically collapsed.

To automatically collapse collections:
http://intermine.readthedocs.org/en/latest/webapp/report-page/report-page/#references-collections
```properties
web.collections.expandonload=false
```

To automatically expand templates:
http://intermine.readthedocs.org/en/latest/webapp/report-page/report-page/#templates
```properties
web.templates.expandonload=true
```
