JBIDE-17849 CSS Hyperlinks aren't working on non-WTP projects

An utility helper method is added due to find pages in projects that are not the WTP ones
(has no web-roots that can be achieved by WTP methods)

Why do you use the full path of the project if the webroot == the project root folder?
For example:
if webContentPath == "/<projectName>"
then container == "/<projectName>"
then the full path of project.getFile(container.append(filePath)) == "/<projectName>/<projectName>/<filePath> which is not correct.
