Updated: mintty 2.7.3

[Thomas Wolff]

I have uploaded mintty 2.7.3 with the following changes:

Character display:
   * Tweaked surrogate handling to facilitate non-BMP display.

Localization:
   * Persisting adaptation of font sample text.
   * Disambiguated translations in different context for "Paste", 
"Font", "Colour".
   * Sorted out en_GB vs. en_US.
   * Fixed localization of Options dialog window title.

It also links to the issue tracker.
