Additional items for Routes

[peterfarrell]

A few items to be addressed for routes:

1. Change requiredArguments parameter name to requiredParameters
2. Change optionalArguments parameter name to optionalParameters
3. Allow for nested arrays in addition to the current value (for lists) for optionalParameters and requiredParameters
4. Allow for EL syntax when defining default values for arguments (i.e. <key name="requiredParameters" value="displayType:${properties.someProp}" />)
5. Ensure that all optional arguments have a default value define as this is a requirement.
6. Added buildUnescapedCurrentUrl() to match all the other build methods that have an unescaped version of itself
7. Add optional third argument in buildRoute() to indicate query string parameters as discussed in the m2sfp
8. Ensure that buildRoute() throws an error if a required argument is not passed and it does not have a default value defined in the route configuration.

FYI, item number 7 is currently breaking the "a" tag in the view tag lib. Please uncomment that "a" test item in the test harness's testViewLib.cfm test page when completing this task.
