/**
* Notes about language registration (for language other than js):
* - All language are expected to register (at least) 2 contract IDs
* @mozilla.org/script-language;1?id=%d
* using the language ID as defined in nsIProgrammingLanguage, and
* @mozilla.org/script-language;1?script-type=%s
* using the "mime-type" of the script language
*
* Theoretically, a language could register multiple script-type
* names, although this is discouraged - each language should have one,
* canonical name.
*
* The most common case is that languages are looked up by ID. For this
* reason, we keep an array of languages indexed by this ID - the registry
* is only looked the first request for a language ID.
*
* The registry is looked up and getService called for each query by name.
* (As services are cached by CID, multiple contractIDs will still work
* correctly)
