Color Manipulation parameters added to snap.properties file

[knowles]

*Note: this pull request involves both snap-engine and snap-desktop, so both pull requests are needed to resolve dependencies.

Enhanced the branding and preference configuration by adding Color Manipulation preference capabilities to the snap.properties file. Adding these parameters enhances the branding capability of SNAP and reduces hard coded differences between the branded package and SNAP. It also adds a convenient preferences setting for users in general.

Modified the wording of Color Manipulation Preferences GUI to better clarify the meaning of certain parameters.

Modified the help pages accordingly.

For the snap.properties file, the following is a list of all color manipulation default parameter keys along with the SNAP default values. These parameters are not needed to be explicitly set in the SNAP package's snap.properties file because SNAP already has them had coded internally.
