Improve formatting in AmlSpec.rtf

* Increase font size from 9 to 14. [Many](http://www.artsassistance.com/best-font-size-websites/) [arti](http://www.adaptistration.com/blog/2013/05/24/youre-still-using-12px-font-size/)[cles](http://www.smashingmagazine.com/2011/10/07/16-pixels-body-copy-anything-less-costly-mistake/) recommend a font size of 16px for body text on websites, and this document will be read on a computer like a web page, so it should follow the same standard. I would prefer 16px, but since you used 9px, I guess you like it smaller. 14px is the minimum I find readable.
* In paragraphs that are mainly prose, not code, use a proportional font (Times) instead of a monospace font (Courier New). Proportional text is easier to read than monospace text, and since this is RTF and not plain text, we can use its multiple-font features.
