Command line arguments -equ and -strequ case weirdness

[Zeturic]

For example, if test.asm contains just:

.warning STRING

And you invoke it with armips test.asm -strequ STRING something, you get an error complaining that the label string does not exist. It works if you invoke it with armips test.asm -strequ string something instead.

It seems like the command line argument parser needs to lowercase the names (like is done in other contexts, such as a literal EQU in source) to make it properly case-insensitive, as it is elsewhere.

This applies to both -equ and -strequ, as the title implies.
