Add --no-multiarch flag to InstallRPackage commands

[labkey-tchad]

Rationale

RLabKey install has been failing on Windows:

[14:48:32][ant:exec] * installing *source* package 'Rlabkey' ...
[14:48:32][ant:exec] ** using staged installation
[14:48:32][ant:exec] ** libs

[14:49:14][ant:exec] *** arch - x64
[14:49:14][ant:exec] ERROR: loading failed for 'i386'

Other R package install methods already include the --no-multiarch flag to avoid this error. Not sure why the build has started failing in this way but I don't think we're too worried about 32-bit support.

Changes

• Add --no-multiarch flag to InstallRPackage commands

any reason why the minor version number went down here?

[labkey-tchad]

The current release is 1.30.0, 1.31.0-SNAPSHOT is just a placeholder for the next release.

[cnathe]

got it. that makes sense
