Instructions on testing.
Increment version number.
Remove redundant code; catch HTTP errors; add session_instance.html preview.
Magic auth tag to allow login, logout and link to account.

Merge pull request #1 from pgib/more-previews

Add more previews
Allow one to set the cache_expiry time (in seconds) for the _attendease_data business. By default, it's 30 seconds, but site regeneration when using --watch can be lengthy if you're just previewing CSS changes, for example.
Increment version.
Merge pull request #2 from pgib/cache_expiry

Add attendease.cache_expiry setting
Only pull down the data when attendease.test_mode is true.
Increment version number.
Was a little over-zealous in what shouldn't happen outside of test-mode. O_o
