Screen flashes & alerts

Added screen flashes that push the background colors and digits towards white when a pomodoro phase is complete

Added screen alerts that progressively lighten the background when a pomodoro or countdown is getting close to completion to alert the user

Added the option to have the background animate continuously when seconds are hidden instead of only animating on every minute tick

Made the loading screen smoothly show the last preset used instead of first loading the defaults and then loading the user's chosen preset

Previously not all values were saved to presets, now fixed by saving all values to presets to avoid confusion about what values are saved

You can type in values into the pomodoro / countdown to quickly enter values instead of clicking multiple times to get to the required number

Values can be zeroed out in pomodoro so that it be used as a countdown

When changing modes, pomodoro or stopwatch stop and save your progress which can be resumed after switching back. The logout and upgrade buttons have been moved to hamburger menu to reduce distraction. Main menu & mini menu pops up automatically when a phase is over or paused

Mini menu z-ordering fixed and clock menu height limited to match the others

Performance optimizations in window spawn process on screensaver launch

Allowed saving pomodoro values to presets for quick access to frequently used timers
