[developers] "Quite" problematic: MRS -> EDS conversion

"Browne was hired a day in January"
- there's a PP-attachment ambiguity here (for "in January")
- but in both cases, we have loc_nonsp between _hire_v_1 and _day_n_of
- we have _in_p_temp between mofy(Jan) and either _hire_v_1 or _day_n_of
- in neither case do we have a link between _in_p_temp and loc_nonsp (which
is what we have in the buggy it-cleft analysis)

"it was a day in January that Browne was hired"
- the correct analysis just adds _be_v_itcleft (to the case where "in
January" attaches to "day")
- the 1214 ERG has both the correct analysis *and* the buggy analysis which
adds a loc_nonsp (so in this case there are *two* instances of loc_nonsp)

If this bug is fixed, I don't think there's any need to look at TENSE.
