Render text of LedCheckBox with default font

Browse Source 
Extend LedCheckBox so that it adds support to render the text with the
default font in the default size. The class now supports two modes:
* Legacy mode
* Non-legacy mode

Legacy mode is the default and renders the LedCheckBox as before. The
font is set to 7 pixels and all the text is rendered with a shadow.

Non-legacy mode uses the current font to render the text. The text is
rendered without a shadow and the pixmap is centered vertically to the
left side of the text.

The non-legacy mode is currently only used in the context of the matrix
LADSPA dialog. Toggle options are rendered using it as well as the "Link
Channels" button.
