Critical bugfixes! Momentus edits of paramount importance crucial to the long-term success of the project

A few tweaks to the readme:
 1. Replaced typographic approximation of em dashes with … em dashes
 2. Made parenthesis surrounding italic text non-italic (yes, it's an improvement — Robert Bringhurst agrees with me [5.3.2 of his book])
 3. Made `project/?` links actually link to the project pages (relative links like `/?` resolve to `/blob/?`)
 4. Replaced code blocks around keypresses with `<kbd></kbd>` as is used earlier in the readme
 5. Fixed new issue link, as in (3)
