Title: [FIXED JENKINS-16660]

[FIXED JENKINS-16660]

Allow variable names with dots in bracketed references.

Given these mappings: and , $A.B would
evaluate to $a.B, as it currently does, and ${A.B} to a-b instead of the
current ${A.B}.

Existing ${A.B}-like references will break (not evaluate to ${A.B}) if
there actually is an A.B variable defined, which I think is very
unlikely.
