Fix probe delete
Fix formatting of probe names

* Allow probe names to be something different from atoms: integer, binary or lists
Allow {apply, {M, F, A}} in static subscribers list

The result of apply(M,F,A) must be a list of legal subscriber
tuples (including possibly {apply, {M,F,A}}.
Added {select, Expr} pattern for predefined subscriptions.

Also, added a start phase for predefined reporters.
The reporters must start *after* the predefined entries have
been registered, in order to avoid a race condition.
