[Markdown Plugin] Auto-completion symbols

[advice2020]

I was making a different post about Auto-completions and this thought came with it.

Markdown uses * symbols for specific formatting
*italic text*
**bold text**

Would be tricky because bold uses two symbols, so might not be possible, not sure if the two ** keypresses entered by user could be detected without conflicting with the single '*' used by the italic formatting?

Anyways, if this is possible, then maybe these two items can also be added into the Auto-completions section / as settings in 'Plugin Preferences'

Thank You
