Changed re revised snippets editor frame.
Fixed some control alignment problems.

Made minimal changes to snippets editor to enable snippet description's active text to be edited either as plain text or REML. Uses new active text editor frame.

Rearranged controls on snippets editor's Code tab.

Modified extra text editor so that multiple paragraphs of text can be entered without using REML mark-up - paragraphs have to be separated by blank lines.
