Bug 13349, editing color scalar value entry box causes wrong color.

The problem is that when processing the scalar value after entry box
editing finished, first of all, there is no checking whether the value is
actually changed, and also if the value is indeed changed, the logic to
update the transfer function is wrong. Fixed both issues.

Fixing development install.

Using install_rpath to fix issue with kwProcessXML instead of using shared
forwarding when running from install directory. This was done with with vtk's
executable renaming rules, shared forwarding was starting to get challenging
especially for compile-tools. This is a cleaner/non instrusive solution. (It may
  need some fixing on Mac, however).
