Preliminary Support for DiscImageChef

[mnadareski]

This PR is a massive amount of work to support DiscImageChef to the same base level as DiscImageCreator. Here is a list of things that it does and does not do:

• Adds paths, command, and flag validation specific to DiscImageChef
• Add nearly all constants and enumerations required for current and future work
• Update other parts of code with improvements from the DiscImageChef parameter work
• Add non-UI setting for enabling DiscImageChef dumping
• NO submission info generation or output file parsing
• NO split file outputs to correspond to DiscImageCreator compatibility
• Edited default paths for both DiscImageCreator and Subdump to reflect the possibility of more supported programs in the future
• Updated DiscImageCreator version for automated builds
• NO automatic building or pulling of DiscImageChef test versions
• Assumes DICF output for all current purposes. Additional format output support will have to take a lot of extra effort
• Unexpectedly does some work for Creator since the version updated again during the course of this PR. One flag was removed.
