Changeset 5879 for CONFIG/UNIFORM/v6/IPSLCM5A2/SOURCES/NEMO/PALEO

Modified Makefile to add configuration PALEOIPSLCM5A2-VLR while retaining IPSLCM5A2-VLR as default configuration for compilation. Moved NEMO SOURCES of IPSLCM5A2-VLR to SOURCES/NEMO/STANDARD and created SOURCES/NEMO/PALEO for PALEOIPSLCM5A2-VLR configuration. Created paleolmdz in Makefile to compile LMDZ sources in SOURCES/LMDZ/PALEO. Added experiments IPSLCM/paleo and LMDZOR/paleo. Added file_def_nemo-lim2_paleo.xml file_def_histmth_lmdz_paleo.xml file_def_nemo-opa_paleo.xml file_def_nemo-pisces_rivers_paleo.xml file_def_nemo-pisces_paleo.xml file_def_orchidee_paleo.xml namelist_ORCA2_cfg_paleo namelist_pisces_ORCA2_cfg_paleo to GENERAL/PARAM for paleo configurations. Set day_step=720 in GENERAL/PARAM/gcm.def_96x95 for paleo configurations. Modified GENERAL/DRIVER/opa9.driver to use namelist_ORCA2_cfg_paleo for paleo configurations.
