Fixed compatibility with Flask's built-in url type-converters

[caffeinatedMike]

Closes #136
Closes #145

With the addition of the model parameter to the render_table macro we can now utilize the previously private macro arg_url_for (previously _arg_url_for) to correctly grab values from each record as it's iterated over during table rendering. This allows users to utilize the built-in werkzeug converters with their url parameters.

Designed with backwards compatibility in mind. Users will still be able to pass in normal url_for calls as well. But, anything involving placeholders would be subject to the new tuple approach.

I know I still need to update the docs, but just wanted to float this out there first for your inputs @greyli @michaelbukachi

Thanks for working on this! I'm preparing a presentation and don't have time to review it right now. I will take care of it at the beginning of the next month.

Nice work @caffeinatedMike! Don't you think it would be better to pass in a query instead of a model? I'm imagining scenarios where users might want to show specific subsets instead of everything in a table, based on certain filters.

Thanks @michaelbukachi! Just happy to be able to help/contribute. Good point! I'll make it a point to adjust it to accept a query, update the tests, and update the documentation once I get the chance over the next couple days. Is there anything specific I need to do to the documentation in order for things to render correctly? I noticed my addition of the custom_actions parameter didn't properly render the inline code (it just left the back-ticks).

@greyli @michaelbukachi Changes made to accept query in place of model. Tests, docs, and changelog updated to reflect and all tests are passing.
