Fix some return types

[distantnative]

• PageActions:: createNum() should always return int, so we need to type cast the result of date()
• Location::num() should also be type casted to a float if only one part exist
• F:: niceSize() never returns an int, always just string
• Iterator::indexOf()always returns the int index position (or false) but never a string key of an associative array, since we use array_key(). This has been the behavior so far, so we're only fixing the description.
• Pagination: ceil() still returns a float, so we need to cast it to an int
• Str::isUrl(): filter_var will return false or the value - so we need to explicitly check that the return is not false

What's the state on this? @distantnative should we move it to the next release or 3.6?

[distantnative]

I just need to add one comment with a todo for 3.6 over the weekend. Then it's good to go. Think 3.5.1 still works

[bastianallgeier]

@distantnative any chance to get this fixed and merged quickly?

[distantnative]

@bastianallgeier sorry totally forgot about this. added the TODO message
