1. Added CRC database lookup for ROM dump validation and file renaming
2. Added delays to improve successful ROM dumping. Especially helps with
2-chip ROMs
3. Fixed database mapper config for Star Trek (not a 2-chip ROM)
This was causing two symptoms/bugs:
* OSCR_LOG.txt was being spammed with random data.
* The size of OSCR_LOG.txt would get so big that copying the log would take a long time, possibly minutes. Oftentimes this caused the display to appear to hang after searching for the CRC (after "->") but before displaying the result.
If using the global log and a version of master since e61ac414d8 you should delete OSCR_LOG.txt from your SD card as it will likely be very large and continue to cause dumping to be slow.
* Reduced PROGMEM / DRAM usage slightly (Using defaults w/HW5: Before -> 214,668 bytes / 5,757 bytes; After -> 213,414 bytes / 5,751 bytes)
* Optimized some menu options and calls
* Added more string constants and implemented them where found.
* Fixed some stylization
* Constants should always be uppercase.
* Features should use the `ENABLE_<feature name>` format.
* Options for features should use the `OPTION_<feature name>_<option name>` format.
* Added ENUMs for more clarity and better type checking.
* Moved some defines over to `constexpr` and `const` types. These are preferred over preprocessor constants when not intended for use with `#if` and other preprocessor language.
A sample `config.txt` is in the SD folder. Currently the option is disabled by default and must be enabled.
Also:
* Eliminated the 5V spike at boot when VSELECT is installed and enabled. See discussion #906
* Fixed a warning in `MD.ino`
* Did some code cleanup, more cleanup to come.
