Code review comment for lp:~mterry/webbrowser-app/less-ubuntucolors

Those changes look good, thanks Michael for taking some time to apply them. A couple of minor comments:

The OK button in src/app/ConfirmDialog.qml should have an explicit color of theme.palette.normal.positive, for consistency. And probably src/app/AlertDialog.qml too.
Not sure what should be done with src/app/BeforeUnloadDialog.qml.

In the history and bookmarks views (wide layout), the color of the current date/folder in the left column when it doesn’t have active focus should be 'selected.backgroundText' instead of 'normal.positionText', according to https://docs.google.com/presentation/d/1Sgf536u5LgKgl41x7xeEeo-XibEEPQZ_phugEArwvec/edit?ts=5728be0d#slide=id.g12f5d7958f_0_92 (that visual design update hasn’t been implemented yet, I’ll get to it soon, but since you’re changing some colors now, I reckon it would be better to use the updated ones now).

Could you please update the dates in the copyright headers for files that were changed?
