Never return stored content from content_for when a block is given
…, inside a body, so you can stream.

* The approach is to compile <% %> into a method call that checks whether the value returned from a block is a String. If it is, it concats to the buffer and prints a deprecation warning. * <%= %> uses exactly the same logic to compile the template, which first checks to see whether it's compiling a block. * This should have no impact on other uses of block in templates. For instance, in <% [1,2,3].each do |i| %><%= i %><% end %>, the call to each returns an Array, not a String, so the result is not concatenated * In two cases (#capture and #cache), a String can be returned that should *never* be concatenated. We have temporarily created a String subclass called NonConcattingString which behaves (and is serialized) identically to String, but is not concatenated by the code that handles deprecated <% %> block helpers. Once we remove support for <% %> block helpers, we can remove NonConcattingString.

…pport::SafeBuffer Signed-off-by: Yehuda Katz <wycats@Yehuda-Katz.local>
This consists of: * String#html_safe! a method to mark a string as 'safe' * ActionView::SafeBuffer a string subclass which escapes anything unsafe which is concatenated to it * Calls to String#html_safe! throughout the rails helpers * a 'raw' helper which lets you concatenate trusted HTML from non-safety-aware sources (e.g. presantized strings in the DB) * New ERB implementation based on erubis which uses a SafeBuffer instead of a String Hat tip to Django for the inspiration.
