[bt-devel] Search syntax help text, html viewer

[Eeli Kaikkonen]

I updated the search syntax help text. It was quite difficult to write 
and it may need correction. Please tell what you think.

I noticed that the html viewer dialog context menu doesn't work. It 
shows items - apparently the default ones from Qt - but most of them do 
nothing. It's possible to open an external web page link in the viewer 
from the RMB menu but not to go back. Gary, would it be easy to make it 
behave reasonably? Being able to copy text is nice, but most other 
options are needless for us, I guess.
