Move ImgLib1's sources to legacy-imglib1

All of imglib.jar's, imglib-ij.jar's, imglib-io.jar's and
imglib-algorithm.jar's sources are merged here with the intent of adding
ImgLib2-compatible wrappers for easier porting.

This is the next step in phasing out ImgLib1.

Let legacy-imglib1 depend on ImgLib2

... because we are about to introduce ImgLib2 wrappers into said
library to ease porting code using ImgLib1 to ImgLib2.
