Implement dynamic colour page

[DechengMa]

This PR implemented dynamic colour page, closes #48

Changes

• Created ColourSection and ColourItem data model
• Implement dynamic colour controller and info pages accordingly

Might need discussion

• I use UIColor.xxx when input as the data source, instead of .plist, and decode RGBA from it. For consistency, we might want to use .plist. But use the variable directly can prevent Apple from changing colour value.
  • I put the colour data source in RevertItem.swift, we might want to move it to another place.

Known issues

• [x] Icon is missing(done)
• [ ] doesn't have nice line break for long colour name.

I can't push my branch to the origin repo: Permission to revealapp/Revert.git denied to DechengMa, may I get some permissions?

After doing some testing, I found an issue:

Notice that the system colors on the squares and the color RGB value is not automatically inverted when changing between light mode and dark mode.

The system colors and RGB value is only inverted if the cell is reloaded.

Nice one! I think I need to set up a listener for theme changes and then reload the data. BTW should we have a button inside the app for switching between light/dart mode?

Oh yes, having a button in app would be nice. I am thinking if you can have a segment control inside the tableview that switches between:

• Default
• Dark
• Light
• Increase contrast [Accessibility]
• Inverted colour [Accessibility]
