Added function to set pagination information
We now create only a single array of results, instead of an array or
arrays or results.
Pagination and Other attributes are now added to the search query.
RedditSearch->get_search_results() now returns a postObject.
Added pagination

Searching now gets 100 results (or 100 for each sub in a subreddit
search), and then after ranking only displays the top 25.
Fixed two bugs

The first bug causes whitlists and blacklists to have empty ('')
elements because of explode.

The second cause an error on bad (or very specific) input that resulted
in less than 25 results.
Removed cloudsearch as an option.

Apparently despite being in reddit's search API, it doesn't work as an
option. Leaving syntax unset uses cloudsearch, so this will be the new
default.
Removed leftover var_export
