Show information about a word-form in pop-ups per each cell in paradigm

[aarppe]

We might want to present multiple types of information for each paradigm layout cell. For instance, the following:

${wâpamêw}+V+TA+Ind+1Sg+2SgO:

• [x] kiwâpamitin: (1) surface word-form without morpheme boundaries
• [x] ki·wâpam·iti·n: (2) surface word-form with morpheme boundaries
• [ ] kit₂·wâpam·i₂ti·n: (3) underlying word-form with original morphemes and boundaries
• [ ] I see me, I witness me: (4) generated English translation of cell word-form
• [ ] 4: (5) corpus-frequency
• [x] (6) human recording
• [x] (7) generated robot recording

For generating the underlying morphotactic representation, we would need to use the specially compiled FST:

hfst-lookup -q src/fst/lexicon.hfst
wâpamêw+V+TA+Ind+1Sg+2SgO	kit2<wâpam>i2tin	0.000000

This underlying form would need to be mapped against the surface form - then the meaning/labeling of the morpheme can be unambiguously retrieved (from a relabeling file):

1	2	3	4
kit2<	wâpam	>i2ti	>n
kit2	wâpam	i2ti	n
ki<	wâpam	>iti	>n

This expands from #1093 to cover information not only on morphemes.
