Checklist for vegan 2.5-0 release

[jarioksa]

I wish to publish vegan 2.5-0 "asap". This "asap" may be as late as 4Q 2017, but with some luck it can be be earlier. There are big changes, and these are mega-issues that must be finished for the release:

• Finish new infrastructure for constrained ordination with several issues to be solved (detecting rank, handling zero-rank components). See issue #218.
• Finish moving to compiled code in anova.cca, potentially with new tests (issue #211).
• Registration and use of compiled code.
• Handle CRAN submission hassle with orditkplot. Closed via 28aeba1.
• getF.c must check input (wrong dimensions in permutations can trash R). Closed via 22fe136.
• decide what to do with capscale: deprecate or keep? See issue #217.

(This entry is the first version of this this issue and rather regarded as a place-holder for future checklist)

I know I haven't looked at the new MLM-based diagnostics yet (but now that summer is here, well spring on the prairies but classes ended anyway, I will look at those), but are you proposing that we merge these or is their absence from the list above indicative?

The MLM statistics were already merged to the master and as.mlm() functions are now deprecated (see issue #234). My main purpose was to list outstanding issues to remind what still must be done.
