[Editor][master] Problematic spell check count with "only mispelled words" option disabled

[Michele Galimberti]

This appears in a development environment after commit c9a4c4b if the option "Show only misspelled words" is disabled. In this case, the dialog title will display a string such as:

Spellcheck showing: 200 of 80 misspelled and 200 total words

with the 1st number bigger than the 2nd.

The best solution is probably to implement a logic to change the string to something like:

Spellcheck showing: {0} total words (with {1} misspelled)

when "Show only misspelled words" is disabled. Maybe even without the parenthesis part

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
