1.1.8: Creation in string, bugs fixes, new pure driver

Fixed:

• Fixed opening an archive with password (#37)
• Fixed UnifiedArchive->getComment() now returns null when comment is not supported by driver (#39)
• Fixed UnifiedArchive->getFileData()->modificationTime is integer timestamp now in case of NelexaZip driver instead of DateTimeImmutable (#38)
• Fixed PharData::create for zip-archives

Deprecations:

• Renamed methods of UnifiedArchive:
  • getFileNames => getFiles
  • extractFiles => extract
  • addFiles => add
  • deleteFiles => delete
  • archiveFiles => archive
  • canOpenArchive => canOpen
  • Old methods are marked as deprecated and will be deleted in future releases.
• Marked as deprecated:
  • UnifiedArchive::detectArchiveType - use Formats::detectArchiveFormat instead
  • UnifiedArchive::archiveDirectory/archiveFile - use UnifiedArchive::archive instead
  • UnifiedArchive::canCreateType - Formats::canCreate

New functions:

• Added method to get file extension for format: Formats::getFormatExtension($archiveFormat)
• Added method to get info about ready to archive files: UnifiedArchive->prepareForArchiving($fileOrFiles, $archiveName = null)
• Added method to create archive in memory: UnifiedArchive::createInString() and BasicDriver::CREATE_IN_STRING ability constant
• Added new pure driver for Zip/Tar(gz/bz2) - SplitbrainPhpArchive.
