t.vect.export using no compression argument results in creation of an archive

[egoddard]

GRASS 7 trunk, rev 61890 on Xubuntu 14.04. In the t.vect.export module, the compression argument indicates that the options are no compression, gzip compression, or bzip2 compression. If no compression is selected, the output is still stored in an archive that cannot be extracted via the file explorer or command line (with tar -x), though t.vect.import can still read the archive. If no compression is used, the pack or GML should be stored in a folder.

Steps to reproduce (Given an existing vector temporal dataset exists):

1. run "t.vect.export input=vector_stds output=~/tmp/export/stds_export compression=no", replace input and output arguments with actual data/path.
2. In the output folder, an archive will exist instead of a folder.

The behavior of the temporal export modules is intentional. The compression flag is related to the compression method used for the generated tar archive. Tests using the latest trunk version indicates to me that the generated tar archives can be extracted using "tar xf stvds.tar".

It is important to specify the suffix of the archive, in this case ".tar", otherwise the file manager may not be able to detect that this file is actually a tar archive.

I added a note on the manual of t.vect.export and t.rast.export in r67965. Please review english before backport
