#45 shell syntax highlighting for i18n strings

[Detlef Lannert]

An i18n'ed string of the form $"some text" gets
displayed incorrectly: The $ is interpreted as the
start of a substitution, the first " is consumed as an
(unrecognized) variable name, and then string / normal
mode are exchanged. The following patch lets joe parse
the i18n string as a string_dq; I could not find any
adverse effects of re-interpreting the character after
the $.
