[WIP] Adjustable accent colors

[boussou]

I just changed some code in src/lib/adwaitacolors.cpp because I wanted it Red.
I suggest adding a define to ease building a custom colored version
like :

//#define MAIN_THEME_COLOR "#3584e4" 
#define MAIN_THEME_COLOR "#E44335" 

then in

static QPalette paletteAdwaita()
{
...
    QColor selected_bg_color = QColor(MAIN_THEME_COLOR);
...

static QPalette paletteAdwaitaDark()
{
...
    QColor selected_bg_color = Colors::darken(QColor(MAIN_THEME_COLOR), 0.2);
...

That's something I would like to see, but I would like to have this configurable by the user, not during compilation. In libadwaita they have various accent colors so next time we do a major Adwaita update, we will definitely include some option for this.

I just shared it because meanwhile it is easy to built it.
