fixed some bugs in INI highlighting

**Fix 1** - Indeneted keys were not highlighted

    [ini]
        indented = true - was not highlighted 
**Fix 2** - If multiple equals (=) exist in key, then string till the last one was highlighted

    [ini]
    key=even_this_was_highlighted=value

For this pull, I have updated (manually!) the minified file also. What tool do you use for the same ?
