gitk: use text labels for commit ID buttons 

gitk maintains a stack of commit ids visited, and allows navigating
these using a pair of buttons shown with arrows using bitmaps. An attempt
is made to recolor these bitmaps to handle different color schemes, but
this is unreliable across multiple themes as the required colors are not
universally known. Let's just use text labels for these buttons,
allowing the themes to recolor the text along with everything else. Use
utf code points for the text, presuming that these arrow glyphs are
available in the selected font.
