DESCRIPTION

• added new setting max_archive_preview_size on rc.conf, it looks like this
  set max_archive_preview_size 20M
• added this setting into ALLOWED_SETTINGS inside container/settings.pyfile like this:
  'max_archive_preview_size': str,
• added parse_human_readable function into ext/human_readable.py file (used for parsing human readable option 20M and convert it into bytes)
• added is_archive_preview_allowed function into container/file.py file. This function gets max_archive_preview_size from settings, compare its value with current file size and returns True or False
• modified has_preview function from the same file. This is modified part:

if self.fm.settings.preview_script and \
                self.fm.settings.use_preview_script:
    if self.container:
        return self.is_archive_preview_allowed()
    return True

this self.is_archive_preview_allowed(self.path) returns true if max_archive_preview_size is blank or equal to zero or if its value is greater or equal to file size. So, nothing is broken. All these modifications affects only on "container" files and only if their size is greater than max_archive_preview_size (and only when preview script is used). In all other cases everything should work as worked before.

UPD:
Modified mkdir from commands.py. Now it can create multiple folders at once
