Allow for custom object-to-string conversions

Some users would like to use formatted output methods like:

scribe.put("Here is my class: %t")

But have that call a custom class-to-inline-string method they define.

This release allows that.

Add an inline method to your class, which will be used instead of the default scribe.inline.
You can implement the custom inline method using scribe.format if you wish.

Bug fix for metadata function

The metadata now also uses the same ordered iteration as the table_string method.
There is also a speed-up for the indent_string method, as suggested on Reddit.
