A small modification to Ghidra 9.0 (initial binary release) to allow mnemonics and operands in the listing to be forced to lowercase in an attempt to mimic IDA visuals.

Forewarning: This simply adds .toLowerCase() calls into code that I have no understanding of. Forcing operands to lowercase in the way that I've done breaks operand highlighting (this is not the case with the mnemonics however).

1. Set the GHIDRA_INSTALL_DIR environment variable to your Ghidra install directory.
   • Windows: set GHIDRA_INSTALL_DIR=G:/ghidra_9.0
   • Linux: GHIDRA_INSTALL_DIR=/usr/local/ghidra_9.0
2. Run build_and_inject.(bat|sh).
   • Linux sh script is entirely untested.
3. Enable the options under CodeBrowser -> Edit -> Tool Options -> Listing Fields.
