update submodules and small fixes to build without errors

[azhang]

• I wasn't able to find any references to basicDomain so I commented it out.
• merge error included in commit
• updated submodule commit hashes
• thrid-party/libjpeg-turbo/jconfig.h the version line gave me an error so I made it a string
• update readme to include appVersion

Manual changes necessary to make it fully buildable:
update Sparkle submodule to use overtake's commit, or use master branch and apply this change:

NOTE: CFBundleVersion needs to be updated to the actual bundle version and the basicDomain needs to be fixed.
