Add type Issue to article feed for eToc scripts

[wtoconnor]

The eTOC scripts need to get an ordered list of articles for the mass emailings. This feed list should reflect the ordering in browse issue.

verified with automatically ordered issue

i still can't get manually ordered issues working.

issue feed does not respect ordering for manually ordered issues at r7548

you can use the AmazonInUse? wiki page to set up a hosts entry for russ.092.small

and then take a look at:

 http://ploscompbiol.russ.092.small/article/browseIssue.action?issue=info%3Adoi%2F10.1371%2Fissue.pcbi.v02.i01

and compare with:

 http://ploscompbiol.russ.092.small/article/feed?type=Issue&issue=info:doi/10.1371/issue.pcbi.v02.i01

you'll see that the ordering is different.

correct URL for an issue feed for a specific issue is:

 http://ploscompbiol.russ.092.small/article/feed?type=Issue&issueuri=info:doi/10.1371/issue.pcbi.v02.i01

parameter is issueuri rather than issue

i've updated the functional spec to conform to the feature :)
