#14 Install directory name chosen based on wrong locale hint

[Per Gunnar Hansø]

When installing Treebeard on an English Windows XP with Norwegian locale, Treebeard install suggest "c:\Programfiler\Treebeard" and not the expected "C:\Program Files\Treebeard".

Used Java 1.6.0_03 and both the jar-install for Treebeard 0.9 and 0.95beta behaves the same way.

Treebeard looks nice, btw :)
