Categories Brought on to the top

There doesn't seem to be a necessity to have a partial. There for
`_req_full.html.erb` it self will be populated with the necessary
HTML/ERB to generate the necessary layout.

Current _req_large.html.erb will be deleted shortly.
Request Bids - to the right side of the view
Bids and New Bid form brought to the right

The right side column is half the width of the container. May be
it could be made smaller?
Content Moved Arround

1. **Due** moved upward ( right below the heading )
2. Meta moved downward

intending ot make it like a blog post were author information is
right after the content with the image. This way concentration will be
on the text, not the authors image.
Meta and Posted by in the footer

Some minor arrangements in the footer. A inline boostrap list style
is used for displaying control links like 'Edit'
Bids form on to the right

Right sidebar:
    [bids form]
    [bids list]

Putting the bids on top would push the form to way below. What would
be important is to have the form visible so a new bidder can easily
make a bid. There for the form is best on top.

In the other hand, existing bids may bot be as important. But having
them on the right side could make the page weighted to the right.

Would be best to add the 'bids' to the left below the author info
by splitting the partial in to two.
Distance - not showing if grater than 300 miles

The code already had conditionals to not show if the addresses
are not provided properly. Added a conditional to  not show if the
distance is grater than 300.
Merge remote-tracking branch 'upstream/master'
Request Large - deleted

The file was created thinking the code would be needed in a new file.
But it seems the existing _req_full.html.slim would be sufficient for
the task and work was done on top of it.
if authorized, allow seller initiated transaction. closes gh-256
Conversion of Distance to integer prior to comparison
keep bids ul even if no bids so jquery knows where to append first bid
Merge branch 'gh-256-seller'
