Currently finding a particular glyph with a given code point is a bit tedious as it requires clicking on the glyph to update the status bar and display the glyph's name and codepoint. A more convenient way to know where we are in the Glyph Map is by seeing a tooltip over the glyph where the mouse is currently hovering over. This patch adds that support by setting the Widget tooltip with the glyph found at the current position in GlyphMapWidget::mousemove_event.
