Options used in all templates should go in a snippet

[mtancoigne]

All the options used in all views (hiddenFields, noToolbar,...) should be checked in <template>/views/common/headers.ctp, and all options used at the end of views in <template>/views/common/footers.ctp.

I started doing so in previous commits with the additionnal JS/CSS snippets

[mtancoigne]

Added a actions/common/common_options.ctp file for stuff common to all actions

For now, this should be great...
