Now uses rss-roller method of creating a combined blog.html full of all
the posts in the post folder. RSS feed is placed on top, this might need
to change when I then split the file into pages.
Put back in abitility to delete rssfeed button if it exists, ensures
compatibility with other mode but depending how this ends up I might
take it back out anyways
Added postdir instead of freetext post
Now functional replacement of old version of script for post -s
postShuffle turned into a function
test for postChunk location works again
script now appears to be functionally identical to previous
