Improved vertical alignment of text in FbTk::TextButton

The old formula for vertical align text inside FbTk::TextButton ('height/2 +
font_ascent/2 - 1') produced not always good looking results, escpecially
when different fonts are involved (eg, ClockTool and WorkspaceName have
different fonts and font-sizes).

'(height - font_ascent) / 2 - 1' produces better results.

Additional changes:

* added ASCII-Art to document the involved entities when calculating the
  baseline
* rewritten tests/testFont.cc to accept multiples texts and multiple
  fonts
* removed some internal parts of FbTk::Font from the public interface
