Changes to more tag in blogCFC for rich text editors

Due to the rich text editor changing the way the <more/> tag/snippet is rendered (it makes it disappear) I've changed admin/entry.cfm to check for [more/] instead.

Change lines 21 and 131 from <more/> to [more/].

If you don't know what "more" does:

<more/>: Sometimes a blog entry may be very long. It is preferable to show only a portion of the entry on the main blog and have the detailed link contain the entire entry. By using the <more/> tag in your blog entry, any text after the <more/> tag will only show up on the individual entry display. You must include the closing / in the tag. When blog entries are emailed, only the text before the <more/> tag is included.

Obviously we use [more/] now not <more/> as take from the docs.

Be careful - The position of this tag/snippet can cause errors with the layout of your blog (as with <more/>) If this tag is placed after say a div i.e. <div><p>[more/] this will cause your blog display to go out of kinder.
