WIP: Ability to set a property value with an enum in shiro.ini file

[bdemers]

SHIRO-425 (applied patch to master)
This enum support could be limited to property only, but that might cause confusion.

Currently supported via this patch:

[main]
myObject = com.foo.bar.Type
myObject.enumProperty = ENUM_VALUE1

This is really cool, but as a user I would also expect the following to work:

[main]
myObject = com.foo.bar.Type
myObject.enumListProperty = ENUM_VALUE1, ENUM_VALUE2

[main]
myObject = com.foo.bar.Type
myObject.enumMapProperty = one:ENUM_VALUE1, two:ENUM_VALUE2

Granted the Map example might be a bit contrived, but less so for the list.

I've added a test for this.

Thoughts ?
