Fix default value not being properly displayed

An option had the value transformer NSNegateBoolean used on it when it
was not supposed to be which resulted in the end user seeing the value
as enabled when it was not actually enabled. As the related option is a
privacy related option, this is considered a critical fix.
Change build version scheme

The short build version is still maintained as 5.0.0, but going
forward, the long build version is now based on the date built. The
build date contains the month, day, and year with the hour built
separated by a period. iTunes Connect no longer allows the same version
number to be submitted twice. This commit is designed to workaround
that.
Update TXURLDumper and no longer include pkg file in repo
Fix error icon image view not positioning correctly on window resize
Update versioning scheme, again

This commit changes it so the version number is not the date of the
build time, but instead is the date of the last commit in the git
repository.

This commit also re-orders the Info.plist file alphabetically and
replaces the version 5.0.0-git with 5.0.0
Change order of new build version scheme
Use /bin/date explicitly in UpdateVersionInfo

Homebrew installed `date` (provided by `coreutils`) uses different command line arguments. This commit explicitly uses the host date binary instead of the first one on the `$PATH`.
