Versioning in GoogleJavaFormatVersion.java does not reflect real version.

In commit 833201c the version was changed to 1.0 and has been static since then. This seems a bit odd with version 1.4 being released afterwards. If it needs to be this way for the intellij plugin to function, that is fine. But I thought it should be brought to your attention.

Sincerely,

#183 addresses this by setting it to 1.5-SNAPSHOT for master.

I merged #183. Thanks @sormuras!

I added a reminder to update it for the next release. It'd be nice to make it more automatic.

You're welcome @cushon!
