New helper ynh_setup_source (#282)

* New helper ynh_setup_source
THE trollest helper :D
An helper to handle download, checksum, copy, patches, extra files and even a way to install without internet connection.
Really usefull to simplify this part of the packaging.
* [fix] Source id and pkg _dir missing, strip-components deactivation
* [fix] Replace tab by 4 spaces
* [fix] False default value in ynh_setup_source helpers
* [fix] Empty var failed on set -u into ynh_setup_source
* [fix] Multiple patch on setup sources helper
* [fix] Doc, patch and extra_file in ynh_setup helpers
* [enh] Allow to use ynh_setup_source in another dir
* [fix] Doc ynh_get_plain_key
* [fix] Missing default value in ynh_setup_source
* Missing closing } after merge with unstable ?

# Download, check integrity, uncompress and patch the source from app.src
#
# The file conf/app.src need to contains:
#
# SOURCE_URL=Address to download the app archive
# SOURCE_SUM=Control sum
# # (Optional) Programm to check the integrity (sha256sum, md5sum$YNH_EXECUTION_DIR/...)
# # default: sha256
# SOURCE_SUM_PRG=sha256
# # (Optional) Archive format
# # default: tar.gz
# SOURCE_FORMAT=tar.gz
# # (Optional) Put false if source are directly in the archive root
# # default: true
# SOURCE_IN_SUBDIR=false
# # (Optionnal) Name of the local archive (offline setup support)
# # default: ${src_id}.${src_format}
# SOURCE_FILENAME=example.tar.gz
#
# Details:
# This helper download sources from SOURCE_URL if there is no local source
# archive in /opt/yunohost-apps-src/APP_ID/SOURCE_FILENAME
#
# Next, it check the integrity with "SOURCE_SUM_PRG -c --status" command.
#
# If it's ok, the source archive will be uncompress in $dest_dir. If the
# SOURCE_IN_SUBDIR is true, the first level directory of the archive will be
# removed.
#
# Finally, patches named sources/patches/${src_id}-*.patch and extra files in
# sources/extra_files/$src_id will be applyed to dest_dir
#
#
# usage: ynh_setup_source dest_dir [source_id]

# | arg: source_id - Name of the app, if the package contains more than one app
