Double border under toolbar on editing/config templates

We have double black border on editing forms and configuration templates (see attachment). This happens because toolbar is one table with bottom border and editing/confuration form is other table (with no top border) with "blue subsection", that has top border. Both borders combined create that effect. Also not all forms start with toolbar OR have subsection before first field.

To fix that we need to introduce css class, that removes bottom border and use it along with "toolbar" class when appropriate.

Also we have grey instead of black right border on configuration sections. This is because it shares it with grid cell class.

Sample section without toolbar is: "Tools -> Service".
