doRNG 1.8

Unit tests are now run through testthat
Minor fixes in man pages and README file
Now depends on rngtools >= 1.3
The result list gains an attribute 'doRNG_version' that contains the version of doRNG that was used, based on doRNGversion(). NB: this is not necessarily the same as the version of the installed package.
Added the following global option 'doRNG.rng_change_warning_skip'. See ?'%dorng%' (issue #14).
Moved dependency on pkgmaker to Suggests to make installation lighter (issue #10).

Enabled running %dorng% loops within a package (incorporating the solution proposed by Elizabeth Byerly in PR#3)
Fixed error with NULL iteration results when setting 'rng' attribute (issue #9)
Fixed error when using unamed foreach arguments (issue #8)
Fixed non-reproducibility issue when the .Random.seed is not yet initialized, e.g., when the session starts and the RNG has not been used yet (issue #12)
Fixed runtime error when package is not attached (issue #13)

Non reproducible %dorng% loop when doRNG is registered over doSEQ (Issue #1 reported by Brenton Kenkel). Actually due to %dorng% not restoring the RNG (to state + 1) when doRNG is registered over doSEQ.
%dorng% was not working properly on loops of length one (Issue #2)

Check error due number of cores used. Now limited to 2 in examples, vignette and unit test.

doRNG now depends on the package pkgmaker (>= 0.9)
improved vignette
most of the general RNG utilities have been incorporated in a new package called rngtools.

when the current RNG was L'Ecuyer-CMRG, unseeded loops now use the current RNG stream as for the first stream in the RNG sequence and changes the current RNG to the next RNG stream of the last stream in the sequence.

fix error "'iter' not found" due to changes in foreach package dependencies -- that was announced by Rich Calaway.
loops seeded with set.seed and .options.RNG were not reproducible when current RNG was L'Ecuyer-CMRG (reported by Zhang Peng)
separate unseeded loops were sharing most of their streams, when current RNG was L'Ecuyer-CMRG the RNG seed.
nested/conditional loops were crashing with a bad error. They are still not supported but the error message is nicer and a work around has been added to the vignette (reported by Chanhee Yi and Zhang Peng).

fixed error when running a %dorng% loop on a fresh session, with no parallel backend registered.

improved vignette
added more unit tests
changed the name of the RNG attribute on result of %dorng% looops from 'RNG' to 'rng'. It now contains the whole sequence of RNG seeds, instead of only the first one.
RNGseq now accepts a list or a matrix describing the whole sequence of seeds. See vignette for more details.
%dorng% loops can be seeded with a complete sequence of seeds passed as a list, a matrix, or an object with attribute 'rng', e.g. the results of %dorng% loops. See vignette for more details.

An error was thrown if using %dorng% loops before using any random generator. Thanks to Eric Lehmann for reporting this.

use R core RNG "L'Ecuyer-CMRG" and the parallel package, instead of the implementation provided by the rstream package.
