Rudder

part of parent ticket, for 7.0 as we can break things

This is a breaking change for 7.0, as it changes the escaping within the Technique Editor - so workarounds implemented in 6.x or earlier may not work anymore

It ensures that the generated technique will:

be correct syntactly (when it's not using rudderc)
    add the exact content of the string typed in the technique editor in a file
    the behaviour of a directive and the technique editor is the same
