Build spgrass6 against grass70-dev

[kalxas]

According to

​http://cran.r-project.org/web/packages/spgrass6/index.html

spgrass6 supports GRASS6+

​https://launchpad.net/~osgeolive/+archive/ubuntu/nightly/+sourcepub/4578743/+listing-archive-extra

Just for the record, the "spgrass6" interface works well also with GRASS GIS 7:

... plots the map as expected.

I spoke to fast: due to a change in some commands like v.out.ogr (1) which is used in readVECT6(), vector data cannot be read right away. The readVECT6() function needs to be updated accordingly (which is a rather trivial task I can help with).

Background: in GRASS GIS 7 a series of parameters got standardized for coherence and ease of use. When in the GRASS session, the commands accept the old parameter names and advertise the new names while this is not possible in scripts.

Update: There is a new, dedicated spgrass7 package available:

​https://r-forge.r-project.org/projects/spgrass/

GRASS 7.0.0svn (nc_spm_08_grass7):~ > R
...
> install.packages("spgrass7", repos="http://R-Forge.R-project.org", dependencies=T)

R Package is called rgrass7 now. I've copied it from ​https://launchpad.net/~marutter/+archive/ubuntu/c2d4u/ , install script needs a matching update, and test.
