Fallbacking of ${content.windowTitle!content.title!} in i18n-ized content

Change By:
Martin Drápela

The mgnl CLI (2.1.0) command
{noformat}
mgnl create-page hello
{noformat}

will produce a FreeMarker file where the <title> element for the page is generated in the following way:

{noformat}
<title>${content.windowTitle!content.title!}</title>
{noformat}

From the author perspective, the command should default to the content of _title_ if nothing is found for _windowTitle_.

In an i18n-ized project, however, this may be rather tricky: The resolver may actually provide a fallback _windowTitle_ value from the JCR instead of the FreeMarker default _title_, even though the content for the _title_ does exist for the given language version of the page.

Thus, under the following definition of page properties,

*The English variant:*
- title:
- windowTitle: This is the homepage

*The German variant:*
- title: "Dies ist die Homepage."
- windowTitle:

the <title> element in the German version will be rendered with the English "This is the homepage".

This could be documented somewhere (i18n / mgnl-cli).

Q for the DEVs: Could this behavior be fixed by making _windowTitle_ a child of _title_ in the class and, consequently, modifying also the print command to fallback to the parent?
