Moved set_alpha to src/image_util.cpp and out of image_32. Added a boolean response to premultiply_alpha and demultiply_alpha so that if it is changed in set_alpha and other locations like the python bindings for composite that the image can be restored to its original state. Removed blend from python bindings.

* Added new configuration options for TIFF:
- method
- tile_height (Default 0)
- tile_width (Default 0)
- rows_per_strip (Default 0)
* Removed 'scanline' configuration option for TIFF.
* Changed RGBA TIFFs to be ASSOCALPHA rather then UNASSOCALPHA

Series of changes for the tiff encoder:
...
* Added configuration options for the TIFF encoder. The options are:
- compression: adobe_deflate(default), deflate, lzw, none
- zlevel: 0-9
- scanline: 1,0 (Forces scanline encoding)
* Fixed bug in encoder with scanline where memory was being modified
* by TIFFWriteScanline. A buffer is now created for each row to prevent
* modification of the underlying image_data.

Fixed error with selection criteria for stripe vs tiled, added modulus check on length and width to select striped in some situations, changed bitspersample for RBGA. (ref #2491 )

Updated tiff processing so now the encoder will utilize different types of data as well as will use Tile based encoding in most situations, if the image is large will revert to scanline based encoding.
