Updated NRML schema readme to point to current documentation.

Moved everything in the current schema to the 0.2/ folder.

This is preparation for the extract of version 0.3.
moved everything into 0.3 nrml schema dir

it makes more sense to put the current (0.3) schema in the 0.3 and then rebuild 0.2 from history

Fixed a git mv error.
Merged master.
Fixed a merge conflict.
Removed QuakeML dependency. It was used only for strike, dip, and rake values.
These are no longer represented by the QML 'nodalPlane' element; instead, they're
just floating point values with some simple range limits.
added 0.2 nrml schema folder; populated with old 0.2 nrml files from history
Found the latest real 0.2 nrml files
cleaned out 0.2 directory; I found a more recent version of 0.2 schema
Resurrected the lastest copy of the real nrml 0.2
Removed 0.1->0.2 tools from 0.3 nrml schema folder.

Added a placeholder for 0.3 tools (since we'll need a few xslts to convert some of the 0.2 files to 0.3)
updated nrml schema references to version 0.3
Moved gml .xsds into gml/ folder (for organization). Updated import references in nrml .xsds.
Moved xlinks xsd into xlinks/ folder. This is an external dependency; we keep a copy locally so there is not network connection dependency.
Deleted an unused GML .xsd file.
Breaking out schema defs into smaller subfiles for better organization.
Split hazard schema into multiple files.

The bulk of the split is done, but I still want to move more of the general hazard schema into the hazard/ folder.
Finished reorganizing hazard NRML schema.
Split risk schema into loss_curve, loss_map, and vuln files.
