Support {height} macro in fourth version part

[clairernovotny]

While the majority of uses can be done with with a major.minor version and the third/patch as the auto increment, there is sometimes a need for a four part version.

If I use 1.2.3 as the version, I get an error:

The value "1.8.5.{height}" is not a valid semantic version.

I believe this should be supported.
