refactor(color): UI layout logic to better handle different screen sizes and orientations

[philmoz]

To ensure correct sizing and placement on large and small LCD sizes.

[philmoz]

The layout handling system has been revised to better support all the current and upcoming variations.

The UI code now operates on three properties:

• Orientation - Landscape or Portrait (determined on ratio of LCD_W to LCD_H)
• Width factor - normal or narrow
• Scaling factor- 80% for landscape with LCD_W = 320, 150% for landscape with LCD_W = 800, 100% for all others.

Orientation is self explanatory.

Width factor is used to adjust layouts where the default font size results in the UI not fitting in the available width. In this case an alternate layout is used that splits the UI elements across more lines. E.G. Outputs, global variables, etc.

Scaling factor is used to adjust font sizes, bitmap sizes and UI position and size co-ordinates to fit the available space.
The scaling is designed so that the default height for controls (buttons, etc) is approx 1.4" (6mm) for of touch operation.

All three factors are set by the UI at build time - the target radio definitions only need to set LCD_W and LCD_H.

Current variants:

• 480x272, 480x320 - landscape orientation, normal width, 100% scaling
• 320x240 - landscape orientation, narrow width, 80% scaling
• 800x480 - landscape orientation, normal width, 150% scaling
• 320x480 - portrait orientation, narrow width, 100% scaling

Can you do a 2.11 PR version for this also... I think it should be fairly minor to rebase against 2.11 as only three files conflicted (color_picker/_editor and startup_shutdown), but you're more familiar with the changes you've been making here ;)

Ummm - you deleted the branch !!!
