Moved hard-coded text in "backend" and "system" to the language files
(English and Dutch). Affected pages: administrator management,
administrator group management, system updates, system settings, email
settings. Also made some strings more generic for general use (like
"Saving...." instead of "Saving administrator account...")
This commit adds a second parameter $attributes to the following functions:
- AssetMaker::addJs
- AssetMaker::addCss
- AssetMaker::addRss
This is useful when dealing with javascript libraries like require.js, which depend on these HTML attributes to function properly.
It does not break the existing code!
