Documentation: correct the meaning of different colors in profile

Browse source 
In commit 0f31b71c3588 ("User documentation - describe the dive profile")
the description of the depth profile coloring was incorrect.

I also fixed some language issue and tried to better describe the zoom
options.

Finally I increased the revision number of the user manual.

The dive profile shown on the main screen is loaded with information.
However, great effort was taken to keep the profile simple, yet
informative.
The main information of the dive profile is the depth graph. On top of
the obvious information of the depth it shows also the ascent and
descent rate compared to average (or recommendation). This information
is given using different colors. Dark red means the ascent or descent
rate is faster than average, dark green means slower than average and
yellow / light green is close to average. The depth graph includes also
depth readings for the peaks in the graph. Thus you should see the
depth of the deepest point and other peaks. Average depth is marked with
a horizontal red line.
descent rate compared to the recommended speed of going up or down in
the water column. This information is given using different
colors. Dark red means ascent faster than 18m/60ft per minute or
decent faster than 30m/100ft per minute. Orange implies an ascent
speed range between 9m and 18m (between 30 and 60ft) per minute (or
descent between 18m and 30m (60ft - 100ft) per minute). Yellow and
light green represent even slower speeds and dark green represents
reasonably stable situations where the vertical speed is between +/-
1.5m or 5ft per minute.
The depth graph also includes depth readings for the peaks in the
graph. Thus you should see the depth of the deepest point and other
peaks. Average depth is marked with a horizontal red line.
The air consumption graph displays the tank pressure and its change
during the dive. The air consumption takes depth into account so that
even when manually entering the start and end pressures the graph is not
a straight line. Similarly to the depth graph the tank pressure
even when manually entering the start and end pressures the graph is
not a straight line. Similarly to the depth graph the tank pressure
gives you information of the SAC rate when using air integrated dive
computer. Same color coding is used with dark red being faster and dark
green slower air consumption than average.
computer. Here the color coding is not relative to some absolute
values but relative to the average normalized air consumption during
the dive. So areas that are red or orange indicate times of increased
normalized air consumption while dark green reflects times when the
diver was using less gas than average. Please note that the color
coding is obviously only possible when a tank sensor is connected and
tank pressure readings during the dive are available.
Water temperature is displayed with its own blue line with degree
markings placed adjacent to significant changes.
It is also possible to zoom in the profile graph. This is done by the
left mouse button and zoom area can be changed by moving the mouse while
the button is pressed down. There is also a toggle zoom under the 'Log'
menu that changes the scale of the dive to fill the whole area, useful
especially for free divers.
It is also possible to zoom in the profile graph. This is done either
by using the scroll wheel / scroll gesture of your mouse or trackpad
or by holding down the left mouse button; the zoom area can be changed
by moving the mouse around the profile. There is also a toggle zoom
under the 'Log' menu that changes the scale of the dive to fill the
whole area, useful especially for free divers.
