v4.0.1 - Nov 2017 - Patch Release

Patch Release of usync

Minor fixes, and hopefully a re-merge of the v7.4/7.5 and v7.6/7.7 releases

• #159 Renaming templates with no children can fail
• #146 uSyncAction file ignored if set to readonly
• #158 branch merge

Some small fixes - also some changes in the back office mean that v7.4/v7.5 sites will now work with v4 - the code for v7.6/v.7.7 has been hidden behind version checks and class libraries so legacy sites will never accidentally trip into it (hopefully!) - meaning we can have a single branch again.
