This version fixes playlist saving issues in High Sierra.

Other than important High Sierra compatibility tweaks, this is mainly a core update to make iRehearse Plus a 64-bit app. This is an important step for the future of iRehearse Plus as High Sierra will be the last MacOS to support 32-bit applications.

NOTE: This transition to 64-bit has broken the operation of the keyboard Media Keys (Play, Fast Forward etc.). We are currently working on a fix for this, however we thought it more important to release a fix for High Sierra issues as quickly as possible.

Now that iRehearse Plus is a 64-bit app, we can move on to working on further updates containing new features.
