Importing a sheet guessed which column was the controller name and which was
the sign text, then silently acted on the guess. On a sheet whose headers it
did not recognise, the guess fell through to "first column", which is usually
the row number — so the destinations came out named 1, 2, 3.
Now the import opens a preview: the two columns are dropdowns, seeded with the
guess and showing a sample of each, above a table of exactly what will be
created. Nothing is imported until it looks right.
The guessing itself is better too:
- a top row of words above rows containing numbers is treated as a header
even when none of its labels are recognised
- with no recognisable columns, the column carrying the longest words wins
- one recognised column stands in for the other, since a destination's name
is usually exactly what the sign shows, rather than picking at random
- a truncated name no longer keeps a trailing space, which would also stop it
matching an existing destination on a later import
Also adds custom sign sizes, for boards that are not one of the three fitted
models. Widths snap to a multiple of 8 since the record stores width in bytes.
