indicator icon(s) - switching

[Sadi58]

I have implemented the following customization on this matter:

1. Created light and dark versions of your png file and renamed them as "dark-theme.png" and "light-theme.png", and symlinked one that suits my current theme as "indicator-chars.png", changing the corresponding file name in "indicator-chars.py" accordingly.
2. Inserted the following lines in "indicator-chars.py":

    DarkTheme_item = self.create_menu_item('Use dark theme icons')
    DarkTheme_item.connect("activate", self.DarkTheme)
    menu.append(DarkTheme_item)
    LightTheme_item = self.create_menu_item('Use light theme icons')
    LightTheme_item.connect("activate", self.LightTheme)
    menu.append(LightTheme_item)

def DarkTheme(self, dude):
os.system("/usr/local/indicator-chars/dark-theme-icons")
def LightTheme(self, dude):
os.system("/usr/local/indicator-chars/light-theme-icons")

(As you can see I've also moved your script to /usr/local/indicator-chars even symlinking it in /usr/local/bin)

Perhaps, if you wish, you can implement this icon switching feature in a better way as I I only know a little bit shell scripting.

Starting with discovery of "pull request" feature, I ended up with a "fork" ;-)
I've made these and some other changes there as you can see.
I'm fully open to your suggestions...
