Fixes for second multi-adaptive benchmark (wave equation).
Seems to work fine now:
CPU time cG(1): 188.093 s
CPU time mcG(1): 45.4958 s

Results look very good:

Newton benchmarks are temporarily disabled: takes longer
time anyway and there seems to be a bug in the multi-adaptive
Newton solver (takes more iterations than fixed point). Also
changed kmax to 1e-3 in bench-domain (works better with new
choice of threshold). kmax is now same for both benchmars and
set in parameters-bench.xml.
