Title: Changed regex handling for commands fv/fvc

Changed pattern matching for commands `fv` and `fvc`. The `findall` method may return a list of strings or tuples(if one or more groups are present in the pattern). For instance, command `fvc (FB|UI).*` fails with
TypeError: cannot concatenate 'str' and 'tuple' objects.
