Use _gspell_osx_get_resource_path() in GspellLanguage
@swilmet
Submitted by Sébastien Wilmet Link to original bug (#761937)
Description
In gspell 0.1, _gspell_osx_get_resource_path() was used in GspellLanguage. But the GspellLanguage implementation has completely changed, the code is now a modified version of GtkhtmlSpellLanguage (to have a LGPL code and get rid of the libxml2 dependency).
