[PATCH] doc: Improve help related to bootstrap script.

[Simon Josefsson]

Hi.  It seems a lot of projects that use gnulib is using our bootstrap
script, but documentation is fairly hidden in the manual.  This is just
a small improvement to the current section.

* doc/gnulib-tool.texi (VCS Issues): Make title more positive,
s/Issues/Integration/.  Some more bootstrap-related hints,
including changing suggested submodule path from .gnulib to gnulib
as this seems to be more wide-spread.
