Juergen Spitzmueller c0000cc405 Improve quotation mark opening/closing guess
Fixes: #8831

This introduces
* a new inset member isPartOfTextSequence() that returns
whether the inset produces something visible at the current position
in the text flow
* an isOpenPunctuation() test that returns whether a character is in the
'Punctuation, Open' unicode class. This is used instead of just checking
for two (Western, ASCII) opening brackets

It also fixes the isChar() and isLetter() value of InsetSpecialChar,
since some types have not been assigned correctly.
