Add "toolbar:bool" RW property for the JS API, fix toolbar visibility

The mozilla plugin has already a "toolbar"(bool) parameter.
For coherency between ActiveX and mozilla plugin, the "toolbar"
parameter has been added to ActiveX, which has created also a
"toolbar" property in the exported API (JavaScript for web pages).
This commit add it to mozilla plugin too, to maintain coherency.

This commit also fix toolbar visibility when toolbar="true" parameter
is used in embed object.
