- There needs to be a space between HTML attributes.
- Ampersand must be encoded on URL addresses
- Div element is non-void, so it cannot be self closed

Preferences: Change of text for unused cylinders.

The present text for configuring the display of unused cylinders simply reads:
"unused cylinders". This is now changed to "Show non-used cylinders in
Equipment Tab". The latter wording is much clearer to the average user.

Use the ENABLE_PLANNER macro in the manual too

This introduces ifdef control structures in the manual too, so we can
continue to develop both the planner and its manual, until its ready for
release.

Fix incorrect behavior in preference window

When doing some changes in the preference window and clicking "Apply", the
'Close without saving' button is supposed to restore the previous values.
However some fields were not restored correctly.

- The Animations Slider was never restored to its initial value.
  (A new member in the pref struct was added - pref.animation)

- The 'Font' and 'Font size' were restored correctly to the previous
  values but their effects weren't restored to the UI and that required to
  open the prefrences window again and press ok.

Change position of heart rate labels on y-axis

The lettering of the heart rate numbers on the lefthand exis "fall off"
the left hand of the profile panel when the panel is a bit narrow. This
minute change moves the letters a bit closer to the Y-axis so that their
left-hand extreme is more or less in line with those of the depth-labels
on the Y-axis. This is a partial response to Ticket # 484.

See #484
