simplify the raw/storage re/rgrep mix
simplify the raw/storage re/rgrep mix

Now there are two modes: storage and fancy (!storage).

If 'storage', the output is always suitable for writing to a file; it
*may encrypt* passwords, but does not modify/translate values otherwise.

 ~ `dump` outputs the whole database in storage format.
 ~ `rgrep` is "raw grep" and outputs search results in storage format.

Otherwise the output may include comments and clarifications, e.g.
follow ref.* links.

 ~ `grep` aka `show` outputs search results in display format.
 ~ `re` prints results in display format, but reveals passwords.

[Originally the whole mess came about since we had a very limited search
 syntax, so there were "search" commands to list multiple items by title,
 and "item" commands to fetch by their number.

 Now the same parser can deal with both – `show` became equal to `grep`,
 and there's no need to keep `rgrep` as a "search" alternative to `re`.]
