Create page from tags issues with description and with only 1 tag existing

[Robert Lyon]

There are 2 problems needing fixing up:

1) The description under the 'Create via tags' field on page settings does not make it clear that multiple tags entered mean create blocks for things tags with all the tags entered.

2) If a user has only one tag in play this tag is selected automatically and can't be not chosen
