Spa Client v3.2

What's new:

• Implemented Hold Mode and Standby Mode buttons.
• Some code cleaning

Hold Mode will allow you to pause your system for minor maintenance up to one hour maximum.
Standby Mode will allow you to run your pumps independently. This mode must be manually deactivated to return to normal. This is a software Service Mode. PLEASE USE THIS MODE ONLY IF YOU KNOW WHAT YOU ARE DOING!

Thanks to @fatuuse for identifying this opportunity!
