Icons and Punctuation between informative/warning messages should be consistent (and respective translations)

Short Description: The several informative/warning messages present different types of punctuation (or lack of it) between them and also different icons within the same type of message.

Expected Result: The icons should be the same for all messages that we defined as warning or informative messages ( if a warning message the icon should be a yellow triangle, if an informative message the icon should be a blue circle) and punctuation should be consistent between them.
