[Tagging] Feature Proposal - RFC - daycare

[Flaimo]

i have changed the value from daycare to childcare, added a list of
some additional tags that can be used and rephrased the definition a
little bit, though i think it will never quite satisfy the different
definitions in every country.

i definitely didn't meant it to be a general tag which also includes
elderly people or call centres for home based care taking. the later
one should rather be tagged with office=*. the way i intended it, it
is as a place where children go to after school to do homework and
then play until their parents with full time jobs can pick them up. if
a native speaker could give a more precise definition, then the
current one i use in the proposal, i would appreciate it.

regards,
