[I18N] Contribution: Timezone independence and argument filtering

                 Key: SANDBOX-167
             Project: Commons Sandbox
          Issue Type: New Feature
          Components: I18n
         Environment: Operating System: All
Platform: All
            Reporter: Armin Häberling
            Priority: Minor
         Attachments: commons-i18n_timezone-filtering.patch

Adding two new features:

1) Timezone independence:
Currently dates as message arguments are only displayed in the default time zone returned
by the method TimeZone.getDefault(). I extended the MessageManager.getText() method so that
one can also choose in which timezone Date arguments should be displayed.

In the current implementation the message template must contain a date or time format so that
the message is formated with the right timezone. That means the template "it's now {0}" will
not work, whereas "it's now {o,time}" will work.

2) Filtering of message arguments:
You may want to include String in message arguments that are untrusted (i.e. user input).
But when you display such a message n a html site it may contain a javascript attack or other
nasty things. Otherwise if you want to store the message in an sql table there are also attacks
possible. Cause of this the arguments should be filtered depending on later use of the message.
For this I created a new Filter Interface and extended the LocalizedBundle so that you can
attach a specific filter which filters the message arguments before formating it. I also did
two simple implementations of specific filters.

Attached is a patch with these two features including unit test.
