Add "Recreate Full Path on Backup" checkbox, Fix DestSubFolder Option

Added

• button for "Add File"
• checkbox for "Recreate Full Path on Backup"
• recreate directory name (but still not full path) when "Recreate Full Path on Backup" is unchecked

Changed

• for DestSubFolder option: when "Recreate Full Path on Backup" is unchecked, the non-blank DestSubFolder is now still used (always use the new modified ReconstructedBackupPath in AddFile, instead of skipping it).

For full details, see CHANGELOG.md (changes are now noted in CHANGELOG.md instead of in README.md).

Installing

• The exe is a standalone icon that can be placed on your desktop (unless you have GNOME 3 without a desktop icons extension)! No installation is required. All settings are stored in your configuration data folder, such as %APPDATA% on Windows.
• On windows, click "More Info" then Run Anyway.
• Avast detects this program in a category of "usually a virus" since it is downloaded from the internet (and possibly because it is unsigned), but as of this moment their cloud is analyzing this version to exclude from their questionable programs category. If you have "CyberCapture" enabled, click "more info" then "Run Anyway." If you do not have that option, go to Avast settings then change CyberCapture from "always block" to "ask".
• Behavior blockers such as Comodo HIPS block running any files downloaded from the internet, so you will have to allow this file when asked.
