missing help page

[andr222]

Unlike many other applications, there is no help site giving all the options available using Qupzilla.
As well as being very useful to new users, it is particularly important for those who, for some reason, have difficulty starting Qupzilla.
(In my case I must have accidently touched f11, making the current page full screen covering even the desktop panel. Unaware that it was f11, Qupzilla was blocked in that mode until I chanced on an issue which mentioned this function.)
I use Qupzilla on Linux.
