Embedded URLs and HTML content

The following files have embedded HTML content or possibly trademarked URLs in them. The contents additionally need to be translated via the locale-specific .po files:

• src/HelpText.cpp
• src/AboutDialog.cpp
• src/SplashDialog.cpp
• src/widgets/HelpSystem.cpp
• src/Menus.cpp
• src/Sequence.cpp
• src/Wavetrack.cpp
• src/AudacityApp.cpp
• src/AudacityException.h
• help/audacity.appdata.xml
• help/audacity.1

Additionally, a lot of scripts are called in the build process; which possibly convert online web resources, for example the scripts/mw2html_audacity/mw2html.py file. It's currently unclear what all those files do, but the build process probably needs to be modified to match the App identifier (as org.audacityteam.audacity cannot be used) and the website probably needs to be done with the new project name as well.

I'd suggest we decide for a name first, then setup a GitHub Organization for it, and then move the repository to it - before those URLs and HTML contents can be changed to match the new project name.
