I've taken the liberty of implementing the suggested new
blankLineContext attribute for contexts.  My patch is attached.

It seems to work fine, but I've never looked at the Kate code (well,
or used Kate, for that matter) before so I may well have missed
something.

While I was there I also changed the lineBeginContext attribute
handling to work with symbolic contexts as well as numeric.  This
attribute doesn't look to actually do anything though??
