Notification of string changes

Author: David Mudrak
MDL-26353 Database activity module: display help icon with the new help strings
This commit makes the new strings added by Helen used at the Import
entries page. Note that the syntax of the strings had to be fixed as
there must not be leading whitespace before the asterisk in Markdown format.

Also as requested by Helen, the wording or export/import links is
improved now.

As a bonus for free, the patch fixes incorrect API usage of get_record()
and friends.
