Create Gradle Task to Automatically Update Local Schedule File

[DanielSouzaBertoldi]

Opening up a discussion for issue #198:

We manually create local files which are bundled with the apps and used until the remote schedule can be loaded. Right now those files are created manually with a script. It could be helpful to automate this as part of the build process.

Initial idea, open to adjustments as I'm not sure what will be ideal:

Create a gradle task which runs the update script
Make build tasks depend on new gradle task
Add the ability to skip this task if we don't want the file to update (if we are using test schedules for example)

Is this too often? do we want to do it only before publish? Are there any risks?
