git-cvsimport: Add -A <author-conv-file> option
This patch adds the option to specify an author name/email conversion file in the format exon=Andreas Ericsson <ae@op5.se> spawn=Simon Pawn <spawn@frog-pond.org> which will translate the ugly cvs authornames to the more informative git style. The info is saved in $GIT_DIR/cvs-authors, so that subsequent incremental imports will use the same author-info even if no -A option is specified. If an -A option *is* specified, the info in $GIT_DIR/cvs-authors is appended/updated appropriately. Docs updated accordingly.
