mustache release v1.0.0

You can add a tarball to any release on Github.  I usually generate the tarball with a `make` rule like
```make
PKGNAME = $(shell oasis query name)
VERSION = $(shell oasis query version)

ROOT_TARBALL=$(PKGNAME)-$(VERSION)
PKG_TARBALL=$(PKGNAME)-$(VERSION).tar.gz

DISTFILES = the files you want to distribute (generated from Git, wildcards,...)

.PHONY: dist tar
dist tar:
	mkdir -p $(ROOT_TARBALL)
	for f in $(DISTFILES); do \
	  cp -r --parents $$f $(ROOT_TARBALL); \
	done
# Make a setup.ml independent of oasis:
	cd $(ROOT_TARBALL) && oasis setup
	tar -zcvf $(PKG_TARBALL) $(ROOT_TARBALL)
	$(RM) -r $(ROOT_TARBALL)
	@echo "Created tarball '$(PKG_TARBALL)'."
```
