more verbose ksp-monitor/snes monitor

[prudhomm]

in complex solver strategies we need to have a fine understanding of what is happening (eg fieldsplit)
the current monitor is not very helpful in deciphering what is going on.
I propose two things:

• date/time to understand the time spent (date my be useful if we don't have it elsewhere)
• the solver/preconditioner prefix

this gives the following
