Rethink Button and Link components

[danoc]

This refers to these four components:

• Button and ThemedLink
• Link and TextButton

Problems with the current components

There are a handful of open issues related to these components:

• TextButton and Link inherit theme have different hover states
• Add support for basic text styling to TextButton and Link
• Link uses inline-block
• Think of how the components that link to pages will work in a SPA world
• Make it easier to use padding with the Link component

And these are issues that aren't already captured:

• Link and TextButton don't allow for 100% width.
• <Link theme="inherit" /> and <TextButton theme="inherit" /> is clunky API and doesn't work for complex layouts.

@dcapo. @lavelle — Does this capture the problems well?

Would also be good to add the event argument to the onBlur and onFocus methods of these components, as we do for others like TextArea and Dropdown
