Some edits to the documentation for absl::Hash as I was reading through it.

Itemized changes:
  * implement -> implements for grammar
  * Fix an incomplete sentence
  * specify *any* type T as opposed to *a* type T ? this is just the language I tend to see for these sorts of concepts in math and makes it more clear that we?re talking about a set of all types T satisfying these constraints
  * add arguments to comine() and combine_contiguous() ? this was mostly because for hash_continuous there was a reference to `size` elements without any mention of what `size` was.
