otherwise.

Do not override Edit>Options>Memory... any longer

Since imagej.git commit 021946ca6f(ImageJ Launcher: parse new-style
ImageJ.cfg), the launcher now prefers ImageJ.cfg over jvm.cfg. This
was done partially to allow ImageJ 1.x to use the ImageJ launcher
(rather than the previous, platform-specific launchers written in
Pascal and C++ or even using MacOSX' JavaWrapper.

So there is no longer a need to write out jvm.cfg in Fiji.

But since ImageJ 1.x refuses to write out a new ImageJ.cfg, we have to
write one ourselves if it does not yet exist.

Memory & Threads...: Fix ImageJ.cfg writing

ImageJ 1.x tries to be clever when parsing the ImageJ.cfg file to find
out whether the memory was specified in megabytes or gigabytes. If there
was no specifier, however, it defaults to kilobytes.

Work around this by making sure to write out the 'm' specifier.

bUnwarpJ: fix bug when using masks included in the input images.

Fixed bug reported by David Richmond that was making the plugin crash when using masks in the second slice of the input images. The problem was in the call to "setProcessor". It had to be adapted to the ImageProcessor type when the input image was a stack.
made some choices for parameters more easy
