Bugfix: quotes in first column do not mean string/atom continuation

Previously, lines starting with a double quote were considered string
continuations, because the double quote was part of the erlangString syntax
object. Similarly, single quotes were considered continuations of quotes atoms.

Now the syntax is changed and the starting quotes of strings and quotes atoms
are considered erlangStartString/erlangStartQuotedAtom.
