I've implemented, but not checked in yet, support for validating param
values against an acceptable list of values.
This is immediately useful for boolean parameters -- we want
'booleanOptionX=garbage' to be a hard error rather than just silently
setting it to false.

Are there other use cases for "acceptableValues" in Remote Commands?

E.g.

before:
@Param(optional=true)
    String enabled = Boolean.TRUE.toString();

after:
    @Param(optional=true, acceptableValues="true,false")
    String enabled = Boolean.TRUE.toString();

At injection time -- if the parameter has a value -- then it is compared
against the comma separated list of acceptable values.
If it does not match any of them -- an Exception is thrown before the
execute() method is called.
