Resolve "separate html from markdown files to proper templates"
What are the differences?
- Remove HTML tags from MD files as possible(For readability)
- hardwares html pages converted to hardware md files
- _index.html converted to _index.md. It included two MD files(/index/core-team.md, /index/story-overview.md).(more controlled,less confused)
- added other channels(facebook,twitter,youtube,wiki,forum)
Closes #36 (closed)
