[bt-devel] Added the Help > About Dialog

[Gary Holmlund]

I have added the Help > About dialog with BibleTime, Qt, and License 
Agreement tabs. Please give any feedback about changes or additional 
items. The BibleTime and Qt tabs have translatable text. The License 
Agreement does not. Even the authors at gnu.org don't translate that one.

I also added a new generic class called BtTabHtmlDialog. It can have 
zero or more tabs. Each view or tab contains a QWebView and can show 
programmatic text or load any local html file or external link. See 
bibletime/src/frontend/htmldialogs/bttabhtmldialog.h for more 
documentation.
