Log:
g.extension: add other source code sources
Local directories supported by copying the data over to tmp dir (doesn't mess with user files and doesn't require changes in the source code). Support for short GitHub URLs. Local zip, tar and other archives and general URLs with archives supported too but not tested. Subversion access still works and is the default. Trac zips are not supported because the files have CRLF in them.
g.extension r.local.relief svnurl=/home/.../grass-addons/grass7/raster/r.local.relief/
g.extension r.sun.hourly
g.extension g.remote svnurl=github.com/wenzeslaus/g.remote
