Cleanup README.md and LICENSE

* Drop the OpenBSD related found in the LICENSE file as we refer
  to BSD 2-Clause License.
* Refer to contributors via the automatically generated list.
* Clarify headers and drop statement that we are running on
  Travis CI which can be easily seen in the build status header.
Contributors as link which is much more readable.
Get rid of obsolete information in README.md

* Drop statement referring to initial Ruby and Ruby on Rails version
  which doesn't provide any helpful information anymore.
* Drop statement encouraging user to seek for help in Rails Guides
  which doesn't make sense anymore as we already tagged version 1.0.

Make post title clickable
Add support to update files via file upload

This commit adds support to update files via the upload file key.
Some usebility changes

- change desing of header so it is less present in the vision
  - remove box shadows and background color
  - use monospace instead of verdana to look fancier
- make post in list view clickable, so it is easier to
  come from list to show
- the main purpose of this tool is to look at posted snippets
  so we increase the size of the post#show area without
  touching the borders
- make linenumber a fixed with so it doesn't look to big
  on big screens. They will get wider in the moment when
  bigger numbers appear (needs to be tested on IE)
- add Date to post view

Thanks to mpf@ to pointing out this issus
