Title: Allows JLanguage::load() to accept an array of $basePath[s] to search

... for a given language file w/ optional fallback to the default language.

Signature changes the default and internal behavior of "$lang = null" to "$lang = true".
The change is BC and has no effect for the "11.4" behavior.

The reason behind this is to avoid bulk calls to $lang->lang() as found en masse in the CMS to find an appropriate .ini file in different known locations.
