luci-base: add support for plural translations and contexts in Lua api

 - Introduce a new luci.template.parser.ntranslate() function which
   takes a count, a singular and a plural translation string as well
   as an optional context argument and returns the appropriate,
   language specific plural translation.

 - Introduce an optional translation context argument in the existing
   luci.template.parser.translate() function

 - Support translation contexts in LuCI template directives.
   Translation messages are split on the first unescaped pipe
   character and the reamining string after the pipe is treated
   as context.

Examples:

 - `string.format(p.ntranslate(n, "1 apple", "%d apples"), n)` will
   return an appropriate plural translation for the given amount.

 - `translate("Load", "The system load")` will return an appropiate
   translation for `Load`, using `The system load` as disambiguation
   context (a `msgctxt` directive in *.po files).

 - Likewise `<%:Load|The system load%>` will translate the word
   `Load` while using the remainder of the string as context.

 - To use pipes in translations strings literally, they must be
   escaped: `<%:Use the "\|" character%>` will translate the literal
   string `Use the "|" character`.

   having to know which classes are builtin and which not

 - Make base classes request any used class explicitely instead of
   relying on implicitly set up L.{dom,view,Poll,Request,Class} aliases

 - Consistently convert class names to lower case in JSdoc to match
   the names used in `require` statements

 - Deprecate L.{dom,view,Poll,Request,Class} aliases

luci-base: Improve change application message

As a native English speaker the luci message displayed when clicking
'Save & Apply' has a somewhat uncomfortable English phrasing of "Waiting
for configuration to get applied".  It could be improved by replacing
'get' with 'be' but once you've got that far you might as well replace
this with the shorter & simpler "Applying configuration changes".  This
is also technically more correct since luci/openwrt should only be
updating/restarting processes that are related to the changed areas, not
changing the entire configuration.

As a result of that, change both the 'success' and 'rolled back'
messages to "Configuration changes have been applied" & "Configuration
changes have been rolled back"
