- Use recent Gradle 1.0-milestone-8 snapshot
 - Add initial cut of build.gradle able to compile/test all modules
 - Update .gitignore
 - Generate Gradle wrapper scripts
 - Remove all Eclipse metadata files
 - Temporarily @Ignore tests that do not pass under Gradle

Prior to this change, the caching reference docs referred to
'root.params', whereas the actual naming should be 'root.args'. This
naming was also reflected in the "#p" syntax for specifying method args.

This change updates the documentation to refer to 'root.args' properly
and also adds "#a" syntax for specifying method arguments more
intuitively. Note that "#p" syntax remains in place as an alias for
backward compatibility.

aspectjrt is a subset of aspectjweaver. Eliminate mentions of aspectjrt
where aspectjweaver is already necessary (e.g. LTW), and do not mention
aspectjweaver where only aspectrt is required (e.g. @Aspect proxying)

Also bump required version of aspect* libs from 1.5 to 1.6.8, reflecting
OSGi and pom metadata.

- now discussing cache scope, test suites, and forking

+ rename cache:definitions to cache:caching (to be consistent with annotations)

The UriComponentsBuilder instance passed into the method is initialized
with current request information including host, scheme, port, context
path, and the servlet mapping's literal part.

Also added shortcut methods to buildAndExpand in UriComponentsBuilder.

If no values are given, the query parameter is removed.

Since dynamic attributes were allowed in Spring 3, it raised the 
possibility to specify a type attribute on a number of the form tags.
Where it makes sense (see below) that attribute is now rejected
and reversely where it makes sense it is accepted.

InputTag allows types other than "text" but rejects type="radio" or 
type="checkbox" since there is a good reason for those to be used 
only in conjunction with the appropriate form library tags.

Other HTML input tags such as PasswordTag, HiddenInputTag, 
Checkbox(es)Tag and RadioBox(es)Tag check the dynamic attributes 
and reject them if they contain a type attribute since.
