Implemented support for passing lists to ignore command and implemented unignore command

[Tranq1]

This PR contains two changes:

unignore command

Added unignore command that enables the user to remove an individual command from the ignore list

list support

Added support for both ignore and unignore commands to accept lists as well, enabling the user to add or remove a set of serials from the ignore list.

Example

@clearignore
removelist mylist
createlist mylist

while findtype 8787 backpack as found
    pushlist mylist found
    @ignore found
endwhile

unignore 0x406DDDCA
unignore 0x406E4F51

unignore mylist

while findtype 8787 backpack as found
    sysmsg found 80
    @ignore found
endwhile
