adding messages to home pages

[moshe742]

• adding a view with the context data that inherits from TemplateView
• adding in the template all that is needed
• changed the urls file to get the homepage class i created on views
• added in the admin the 2 pages (on the server, can delete if not approved)

This has two problems:

• if there are no pages titled "messages" and "messages_hebrew", the view will raise a DoesNotExist exception and the home-page will show a server error
• If someone puts ---- in the message text, e.g. to separate messages, then the messages will miraculously disappear

I suggest, instead, that the view will look for the pages, and if they aren't there, that will be the mark that there are no messages. The messages can still be always present in the database, just with a changed title.
