Omaha 1.3.29.5 available on github

[Sorin Jianu]

Hello everyone,

we've pushed a couple of commits to Omaha to allow for dual signing of Windows binaries as a response to SHA1 code signing deprecation.

We've also pushed a patch to make the installer more resilient to DLL side loading issues, such as https://code.google.com/p/chromium/issues/detail?id=116722 or 

Best regards!
