[Seaside] Seaside-REST Jürgenized

[Philippe Marschall]

Hi

Lukas Jürgenized (Dale should know what this means) Seaside-REST.
 - pragmas are now lower case like everywhere else, there is a rewrite
rule helping you migrate
 - the *PragmaBased* classes are gone, that's now the default behavior
 - caching is off by default which makes development much easier, you
should still turn it on in production because it accesses the source
code which is slow and not thread safe (just implement
#shouldCacheRoutes)
 - methods can directly return something that understands
#seasideMimeDocument, that saves you requestContext respond:

The wiki page has been updated [1] and there's an upcoming chapter in the book.
