Minor, or patch version numbers with leading zeroes don't work

[shannah]

Discussed in #151

If your release version has a leading zero one of the parts, the app will fail to launch because it will normalize it out.
E.g. Version 27.11.07 will be normalized to 27.11.7. This causes problems because it uses the normalized version in some places and the un-normalized version in other places.

Will need to investigate before I decide the best way to fix this.

For now, the workaround is to not use leading zeroes in parts of version numbers.
