[lmi] Group quotes: effective date in "Plan Summary"

[Greg Chicares]

Vadim--Because you're reworking the "Plan Summary" box, would you
prefer that I send you patches like the following, rather than
committing them directly? Here, in particular, I'm not sure whether
you want to rearrange the order of struct global_report_data members,
and I didn't want to make that any harder.

This patch gets "effective date" from input instead of setting it to
the current date:
