Bug 507073: [content assist] Use fitting colors for Content assist's
additional info pane

Part 1:
HTMLPrinter should use default JFace colours suitable for presenting
information rather than that of tooltips (INFO_*).
The reason is on Gtk, tooltips have black background and white text,
making it hard to read information. (See screenshot in bug).

This makes Code-completion's javadoc window have suitable colours
on gtk again (See screen shot in bug).

On Windows/Cocoa, there is no change in behaviour. This is Gtk specific.

Test (gtk):
- Launch child Eclipse
- Type "Obj", then ctrl+space (keep pressing ctrl+space till "Object"
  appears as an option)
- Inspect javadoc popup.

Before: Black background/white text
After: White background/black text:

NOTE:
- This may make some darktheme elements appear white-ish in some cases.
Part 2 (see bug) addresses the case for the javadoc info additional
plane on Dark theme.
For other elements, similar strategies should be used to call
HTMLPrinter with colours suitable for darktheme.
