Boxee web browser is unable to send 'Enter'/'Return' key code to web servers as part of text entry

When the boxee web browser is used to fill text into a text entry field on a web page, the keys for 'Enter' == 'Return' == DPad center button, which all use the same key code, are reserved for the purpose of opening or closing Boxee's virtual keyboard popup. So there is no way to send a real 'Enter' key code to the web server handling that page. This may not matter on pages where the action related to the entered text can also be triggered by some web page button, but sometimes that is not the case. For example, the main search text box of "TheTVDB.com" has no associated button, so the only way to start a search of the entered text is for the web browser to send an 'Enter' key code to the web server, while the text field is selected. But that is exactly what the Boxee web browser is unable to do.

This makes it impossible for the Boxee web browser to start any web page actions that depend on an 'Enter' key code at end of a text entry.

One simple way to fix this would be to add a new virtual button to the virtual keyboard, such that using this button would perform two different actions. First it should close the virtual keyboard popup, just as when pressing the normal 'Enter' key (or DPad center), but then it should also send the 'Enter' keycode to the web server.

This simple change should eliminate the problem, adding Boxee compatibility to a huge number of online pages that are currently unusable by Boxee.
