Refactor the most recent widget

[wjhdev]

• Recent posts now outputs one consistent dom type (unordered list).
• Added new image alignment setting.
• Removed medium image option (it outputs the same as large image)
• Commented widgets.less
• Fixed padding issues.

Before we merge in, it might be worth looking at with @kaeti to see if we can make some immediate UI improvements for 0.5.

Here's what a couple configurations look like.

#1

#2

#3

#4

#5

@willhaynes This looks good to me. I notice that there are changes to widgets.less but no corresponding css file was changed. Do we need to recompile any css for this?

[wjhdev]

Yeah. I didn't commit css to avoid merge conflicts.

[rnagle]

Cool. Feel free to commit the CSS in the future. Since presumably we're not editing those files directly, any merge conflict can be fixed with grunt less.
