data - add A2BFlip data

Add summary, description, images, and metadata for a puzzle game.

Next steps are to add one or two more of each category then create
a generator that takes an arbitrary set of data.
gitignore - ignore generated HTML files

Markdown will be the canonical store for summaries/descriptions.
a2bflip - add screenshot, refactor YAML metadata
issues - start tracking issues found with the games
arrowheads - initial commit of all data
1check - initial commit of data
abalone - initial commit of data
build - initial commit of build script and changes required for it

Right now can generate an 'output' directory full of static
HTML, CSS, and images. You get a stub index page, one page per
category (apps, board, ...) with each game/app having a screenshot
and a summary, and a deail page for each game/app.

Next step is to give each game/app download links etc.
readability - reduce line length, increase line height

Trying to improve the readability of the large bodies of text.
game summary - add download links and last updated timestamp
boxes - initial commit of data
circolar - initial commit of data
colourama - initial commit of data
findpat4 - initial commit of data
readability - reduce header size, reduce line height

Went a little overboard, was causing too much scrolling.
Game summaries - Open 'Read more' in a new window/tab
Game details - add Disqus comments to all detail pages
game summary - fix anchor links in left sidebar to jump to right place

Due to the fixed top navbar you need to jump to a location 50px above
the game summary heading. Use an invisible anchor link offsetted
by -50px and jump there instead.
Base - add DNS prefetching for all domains used in site

In particular Disqus comments fetch a shed load of resources all over
the place so prefetch DNS records for thos records.
Base - add MSIE9 Pinned Site tooltip for Mindgames site

If a user pins the site to the Start Menu or the Taskbar mousing
over the pinned item shows this text as a tooltip.
