Add mechanisms to reformant and check code style (#128)

Use an internal version of astyle (astyle 3.0). Scripts taken from QGIS.
astyle.options from https://github.com/uclouvain/openjpeg/issues/128

scripts/prepare-commit.sh can be used locally to automatically reformat
edited files.

Travis-CI will run scripts/verify-indentation.sh to verify committed files.
