make InsetListings ready for dialects, part 1 (joint work with Bo Peng):

* src/insets/InsetListingsParams.cpp:
	- complete list of languages/dialects
	- fix some typos
	- (validate): check for braces

* src/frontends/qt4/QListings.cpp:
	- fix list of languages (not yet complete)
	- make it possible to enter [dialect]language in the advanced widget
