Added Go Book Supporter ACTIOTECH and CLEANUP WORKS

Added ACTIOTECH to Go Book Supporter section in both home page and supporters page

Clean Up includes the following:

1. Removed /less folder which is not required. We have compiled CSS instead
1. Removed /assets folder as it is not used. We /images instead
1. Index.html is huge, we split them into multiple files and called them from index
1. Extracted all JS calls and script tags in the footer.html partial and moved it into a js partial for better maintenance and reusability

We have moved our staging server to github pages and as a result we had to customise some settings to host the same repo on both gophercon.in and qwinix.github.io/gopherconindia.github.io. It has been taken care. The steps to deploy is now documented in README. We will continue working on improving it.
