Upgrade ECM version requirement to 1.0.0 after all.

The "+ 1" was causing an unsigned value to be cast to a signed value,
which was then compared with an unsigned value, causing the warning.
Making the constant unsigned fixes this.

+The following image formats have read-only support:

+- Gimp (xcf)
+- OpenEXR (exr)
+- Photoshop documents (psd)
+- Sun Raster (ras)

+- JPEG-2000 (jp2)
+- Personal Computer Exchange (pcx)
+- SGI images (rgb, rgba, sgi, bw)
+- Softimage PIC (pic)
+- Targa (tga): supports more formats than Qt's version
