[IMP] implement .alike suffix on props

Browse Source 
It is common in Owl components to have anonymous function as props.
However, since each rendering create a different (but equivalent)
closure, Owl will consider the props different, so will update the child
component, but this is (often) not necessary.

This commit will help reduce the problem by introducing a new `.alike`
prop suffix, that will let Owl know that each version of that specific
prop should be considered the same, so, will be ignored by the props
comparison code.

closes #1360
