Add shell globbing

[vinc]

Add support to the shell of filename expansion or globbing for * and ? wildcard characters, where a pattern given in an argument of a command will be replaced by files matching the pattern.

• * means zero or more chars except /
• ? means any char except /

For example /tmp/*.txt will match any files with the txt extension inside /tmp, and a?c.txt will match a file named abc.txt.

[vinc]

Only the delete command support multiple filenames as arguments for now.
