Pass ActiveSupport::JSON.decode a string and not an IO when interfacing with GitHub API

In older versions (< 4.1) of ActiveSupport, this worked because
ActiveSupport used MultiJSON, which would invoke #read if it
responded to it (https://github.com/intridea/multi_json/blob/v1.8.4/lib/multi_json/adapters/json_common.rb#L9).
However, newer versions of ActiveSupport, starting in 4.1, use
ruby's standard JSON gem (https://github.com/rails/rails/commit/ce4456fde6f45f1abd020cbdeb520d401299e01f),
which expects a String. Reading the IO that #open returns
to us and passing the resulting String to JSON.decode ensures
compatibility with all versions of ActiveSupport.

Fix a bug that link_to_next_page behaves like link_to_previous_page

This fixes #530
Do not use prev_page/next_page's options

it has extra keys like :current_page and :total_pages. Just pass the
original options so their behaviours don't change from version 0.15.1.

Also, {remote: false} doesn't have to be merged since options are passed
to link_to_next_page/link_to_previous_page directly.

Ruby 1.8.7 doesn't like the new hash syntax...
:disappointed_relieved:
Squash "warning: ambiguous first argument; put parentheses or even spaces"
Change 'previous' to 'prev'

"previous" is treated like "prev" by most user agents(maybe), but since
"prev" is officially listed in the specification:
http://www.w3.org/TR/html5/links.html#linkTypes, it should be used
instead of the long version.
PrevPage and NextPage don't use total pages and per page values
Use NextPage and PrevPage to generate link tags for rel=next and rel=prev

fixes #535, closes #509
Add "describe 'Tag'" block
Variable name 'i' isn't a good name, it represents the number of the page
Issue #310 fixed. Refactored code to use a single method to know if a tag page should be displayed.

310 - Fixed. Need to write some tests now.
