Fixes a concurrent write panic that occurs when you switch pages quickly while in dev mode.
The fix uses a RWMutex to allow multiple template readers, but only one active writer. When not in dev mode, the only write to the templates map is when NewPages -> loadAllTemplates is called. When in dev mode the loadTemplateFromDisk is called and will load items into the templates map.
When in dev mode. Concurrent writes to the template map will cause a
concurrent write panic and crash appview. Quickly moving between pages
can trigger this crash. This is addressed by adding a RWMutex on the
templates. RWMutex allows multiple readers, but only one writer.
