Altered the ProjectCreateForm to include a message at the title box that explains the limit of 100 characters.

Altered the ProjectCreateForm so that an alert is issued if a user adds 5 tasks.  This warnes that the project creation process can take a little while and that they should not click Create Project more than once.

Added links to style sheets in polymer templates. This fixes the issue of not properly displaying styles of polymer elements that Dart generates (e.g. Task stream).
Following options were attempted prior to including the links to the style sheets in Polymer templates.

-adding bool get applyAuthorStyles => true; to dart
-adding Polymer('task-stream'), { applyAuthorStyles: true }); to template
-noted: applyAuthorStyles is deprecated (Feb 2014)
