Saving in a separate message window and closing it before the save is done

With this change the EHTMLEditorView is using the colors from current theme.
Unless the newly introduced option "Inherit theme colors in HTML mode" is set
the colors are not sent in resulting HTML formatted message (white background
and black font are used).
With this patch the visited links (opened with Ctrl + Left click) are marked
as visited with the possibility of changing its color in Page properties dialog.
Follow-up fix that fixes the leak of two strings introduced with

The application/postscript mime type had been handled by the text-hightlight
module, but thinking of it, it doesn't make much sense, because most users
would prefer to see the content rather in a postscript viewer, than
the source of the postscript file, thus this change removes the mime type
from the text-hightlight module. There had been also issues about thinking
that certain parts had been handled, while they did not, which this change
fixes as well.
The issue had been reported downstream at:

There could happen a busy loop on a Month view select, when the week
starts on Sunday was set. The date range clamp made the first day Sunday,
but the Month view itself corrected it to Saturday (it doesn't split
weekends), this was noticed and the time range was recalculated
again, by six days back. Then the round repeated down to 1970, till
a runtime critical warning wasn't hit.
Since this change the client is responsible to provide credentials
to use to authenticate backends (through ESource-s, to be more precise),
unless the credentials are already saved.
