• Fixed output of --version command (thanks @kroegerama)

• Include SPIFFS source code as a submodule
• Use SPIFFS_ALIGNED_OBJECT_INDEX_TABLES=0 by default, set to 1 in -no-magic-length builds.

Changes

1. Update SPIFFS to f5e26c4 (fixes creation of files larger than 24k)
2. By default, don't include the following files/directories: .DS_Store, .git, .gitignore, .gitmodules. New option (-a) is provided to allow these files/directories to be included.
3. Provide two versions of the binaries for each platform: normal one, and the one with "no-magic-length" in its name.
   • Normal version is compatible with the applications which use SPIFFS_USE_MAGIC_LENGTH=1.
   • "no-magic-length" version is compatible with applications which use SPIFFS_USE_MAGIC_LENGTH=0.

• Unpacking fixes (#13, #22)
• Fix adding files with names starting with a dot (#14)
• Update SPIFFS to 0.3.7 (#23)
• Append compilation flags defined on the command line (#19)

• pack files recursively
• unpack files from spiffs image
• add debug output option and some error checking
• update to SPIFFS 0.3.3
