[ANN] Rearranger version 4.7

The plugin:
- rearranges (reorders) class and class member declarations according to a user-specified order and/or method call hierarchy;
- generates section-marking comments;
- provides several controls for spacing within and between methods and classes; and
- permits the user to manually rearrange items.

This is a bug fix release, addressing these issues:

1) eliminated a String-related exception when trying to arrange a class with a method named "set" and a single parameter. (Code was looking for a property name to follow "set" but there was none.)

2) fixed comment fill string expansion problem when string contained leading tabs; these were being counted simply as one character each. Now their apparent width is calculated properly.

Thanks to Hans Häggström and Thomas Singer for the bug reports!
