[Interest] qsTr in components

[Shantanu Tushar]

Hi,

Instead of using ID-based translations, yo can just use qsTranslate[1] and
specify a good context yourself. Here are some examples on how I use it-

text: qsTranslate("Tournaments", "Prize: %1 %2")
text: qsTranslate("Actions", "Logout")
text: qsTranslate("Screens", "Settings")

I find it much more readable than the ID-based option.
