[fix] Fix optimist project url in README
Fixes #84, #85, #86

url validation should be done in `ecstatic.js` (#85)
Fix redirect location (use `parsed.pathname` instead of urldecoded `pathname`) (#86)

Fix encoding of href genereated in `writeRow()`, no longer need `decodeURI()` (hence error check) here (#86)
Query string is appended to href (if applicable) (#85)
Use html5 doctype and utf-8 encoding (#84)
Use `<table>` to in `render()` (so we can add more columns later on)
Add '/' to dir entries (both link and display name)
Add some comments
Fixed some linter warnings

Fixed test case for 'subdir_with space' (#86)
Added test case for non-ascii url (#86)
