Bugfixes

Bug with "Required" option is fixed. Bug with handling of user specific configuration files is fixed.

Support for required options and options with additonal checks is added.

Now option types can be one letter (S, B, I, A, N), short (Str, Bool, Incr, Num), or full (String, Boolean, Incremental, Number), for better code reader experience.

Options can be marked as required (R, Req, Required):

 parse_arguments  '-f|--foo)FOO;String,Required'  '-b|--bar)BAR;S,R' -- "$@" || exit $?

Additional checks can be added to options. Checks are executed after argument parsing cycle. Example:

'-f)FOO;Number,Required, (( FOO > 2 ))'  \
'-b)BAR;Number, (( BAR > FOO*2 ))'  \
'-B)BAZ;String,Required, [[ "$BAZ" =~ foo* ]]' \
...

Dependency on perl is removed

• Small cosmetic fixes.
• function END is added again for better looking code
• dependency on perl is removed from spec file, so containers will be smaller but help text will look ugly.
