git-svn init/clone --stdlayout option to default-init trunk/tags/bran…

…ches

The --stdlayout option to git-svn init/clone initialises the default
Subversion values of trunk,tags,branches: -T trunk -b branches -t tags.
If any of the -T/-t/-b options are given in addition, they are given
preference.

[ew: fixed whitespace and added "-s" shortcut]
