And some equipment:

• Male, female and pregnant shortsleeved shirt
• Female tight dress skirt
• Female fancy skirts and fancy corset
• Female straight skirt
• Male and female belly belt

Moved skirts to jacket slot, in order to avoid issues with shoes.
Jacket slot named 'coveralls'

Now, the application stuff:

• Fixed some bugs in the character randomizer code.
• When the mouse cursor is placed over a combobox, PGUP and PGDOWN keys will cycle through the combo options.
  Good if you want to see all the options without constantly opening the combobox.
• The UI can now be scaled. In the chargen.ini file, the parameter "gui_scale" sets the value.
  (Values other than 0.5, 2.0, 4.0... will generate some 'jagging' in the ui textures).
• Projectiles are now shoot in the direction of the mouse cursor. The character still can't shoot behind or to the sides, only to the front, but now in a certain angle.

That's it for this update. Have fun.
