[Abel Deuring]

This branch fixes bug 588276: "Enable use of bug_reported_acknowledgement in web UI"

It adds the field bug_reported_acknowledgement to edit forms for IDistribution, IDistributionSourcePackage, IProduct, IProjectGroup; FileBugViewBase.submit_bug_action() now tries to retrieve the bug filing acknowledgement message from the bug target and its parents. This is done in the new method getAcknowledgementMessage().

The property bug_reported_acknowledgement is defined for all bug targets, but only the four bug target types IDistribution, IDistributionSourcePackage, IProduct, IProjectGroup have database columns for it; other bug targets (IProductSeries, IDistroSeries, ISourcePackage) inherit it from their parents.

This acquisition logic is fine, but it ignores the case that a customized message is defined for a project group but not for a project within the project group, or for a distribution but not for DistributionSourcePackage. We should show in this case not the standard messae, but the message defined for the project group or the distribution, respectively.

Hence I duplicated/generalized the "acquisition logic" in the browser class method getAcknowledgementmessage() so that it works for DSP -> distribtuion and product -> project group too.

tests:

bin/test -t test_bugtarget_filebug (for getAcknowledgementmessage())
bin/test -t xx-bug-reporting-guidelines.txt (changes edit forms; shows that the notification shown in the web UI when a bug has been filed is customnizable).

no lint

Minor grammatical nit pick: "does not have a" reads better than "has not a".
