REVISION SUMMARY
  A plugin implementing ILanguageSupport can specify the language supported
  by the plugin JSON metadata key "X-KDevelop-Language", which is specified
  to only take one string item.
  The only known effective user of this metadata is the filetemplates plugin,
  which takes the "Language" property of a to-be-applied template file to ask
  the language controller for a matching language plugin, to get a proper
  class helper object for the code generation.
  
  KDevCLang currently has its "X-KDevelop-Language" metadata set to "C",
  while it can support C, C++ & Objective-C. As a result the language
  controller currently will not deliver KDevCLang to the filetemplate plugin
  when asked for "C++", which then flaws the generation of C++ classes.
  
  This patch introduces a new key "X-KDevelop-Languages" (for semantic correctness)
  to fix this, and emits a temporary warning to help anyone to port their
  language plugins as needed.
