Bootstrap script

[arcticicestudio]

Implement the boostrap script to run the snowsaw.
This should include constants to runsnowsaw:

Constant	Value	Description
SNOWSAW_DIR	.snowsaw	Path to the snowsaw submodule.
SNOWSAW_BIN	bin/snowsaw	Path to the snowsaw binary.
SNOWBLOCKS_BASE_DIR_NAME	snowblocks	Name of the base snowblock directory.
SNOWBLOCKSDIR	.	Absolute path of the current working directory the bootstrap script runs in.

The actual execution command "${SNOWSAW_DIR}/${SNOWSAW_BIN}" -s "${SNOWBLOCKSDIR}" should allow to add additional options via "${@}".
