Add 'modis_30s_lake' for MODIS 20-class with lakes dataset to GEOGRID.TBL

[mgduda]

'modis_30s_lake' refers to the dataset created from the 30-arc-second MODIS
20-class dataset with algorithmically added inland water bodies, and which also
has corrections to remove spurious water points over Antarctica.

This commit also makes the 'modis_30s_lake' dataset the default.

For aesthetic reasons, most lines in the LANDUSEF entry have been modified
to align the ':' character; these other changes (beyond the 'modis_30s_lake'
lines) should be purely whitespace changes.

@mgduda
Thank you for including the output from the git diff -w command, it makes the comparison much easier

Also, tricky name: 20 class with lakes.

@weiwangncar When you have a moment, could you review this PR and approve it if you have no objections?

[weiwangncar]

I'm ok with the change.
