Colored output for sh and shell commands

[jhmaster2000]

This can now be achieved since Discord added (limited*) support for TTY color codes on ANSI codeblocks. It's currently desktop only and probably will stay that way for a long time considering the history of syntax highlighting on mobile, therefore a new --mobile (short --m) flag needs to be added to both commands to strip color codes so they don't leak and trash the mobile output.

The child_processes themselves also need to be able to receive the color codes, in a crossplatform (Windows & Linux) way. Refs:

• apt install expect & unbuffer <cmd> (Linux only?)

• Discord ANSI codes are limited in the following ways:

• Only primary colors work, not secondary.
• Extended color doesn't work.
• Some colors don't really match their official ANSI name.

Example codeblock (ANSI):

�[1;30mC�[31mO�[32mL�[33mO�[34mR�[35mM�[36mA�[37mT�[31mI�[34mC
