DGDS: drawType2 improperly searches for a title.

[BehindTimes]

drawType2 currently searches for a colon (:) to find the title, and if there's no colon, it just assumes it's all text.

The dialog when looking at the city hall though has a colon later in the text, which needs to be displayed as text, rather than having an extremely long header which runs outside the bounds of the dialog.

This could be corrected if, when searching for the colon, the colon appeared before any carriage returns (\r), and if not, the colon would be part of the text.

In 564747e3:

DGDS: Only search for title before CR

Colons are allowed to appear in the dialog string if they appear after a CR.

This fixes #15535.
