The alt button in Linux is more often than not used to move the window (through clicking and dragging while holding alt down). When that's the case, the window manager will not notify the application of alt+click events. This commit replaces alt+dblclick with shift+dblclick under Linux.
Issue #13: TODO extracting doesn't work This bug appeared, if the user uses a locale with non-ASCII characters in date / time texts. Since UTF-8 is (IMHO) the default encoding of Sublime Text 2, explicitly decoding the result as UTF-8 should now return a valid unicode string and not longer raise a UnicodeDecodeError.
