User Manual: Minor updates to text with 4 image replacements

Minor grammatical and stylistic text adjustsments, following quite a
few changes to the text by several contributors over the last two weeks.

Four images are replaced to reflect the latest UI, and also to
reflect the Gnome 3 rendering. These relate to
the specification of cylinder gas in the Equipment Tab.

Don't zoom the profile when the left button is pressed

This prevents zooming out to more than max in the planner. Using a Mac
MagicMouse it happens at times that the finger slides on the mouse while
dragging a waypoint which can result in zooming out further than max.

Fixes #695
