A few files snuck in with CRLF for the line endings. These make it hard
to look at diffs as every line appears to have changed. This commit
makes only line ending changes, so can be ignored
This is particularly important when bulk adding (by director, etc.)
as otherwise the user might end up having to click OK to many
many error dialogs.

Factor out the FP_LIB_TABLE specific content from FP_TBL_MODEL into a new
LIB_TABLE_GRID class that can be used for any library table grid mix in.
Create new FP_LIB_TABLE_GRID object for the footprint library edit dialog.
Add method GetEnvVariables() to return any environment variables found in
a LIB_TABLE object.
