2aba64b itself reverted diawrap.cc to an olderversion. Undo those changes.Additionally remove all diagrams tests, these will be replaced later. But fornow we need a commit which passes the test suite.

These pass a large number of comparisons with qgraf, using@tueda's "qgraf.frm" comparison procedures.

With this change, the diagram filtering is compatible with qgraf's output.
This passes many tests (to come, for the test suite) of single keywords.
Currently there is a difference, to be resolved, when specifying both of a "dual option". For example, specifying "onepi + onepr" in qgraf results in 0 diagrams. In FORM the options cancel each other, and everything is generated. A change to grcc is required to resolve this.
