[raster] README.raster needs updating or removal

[dustymugs]

README.raster found in root of trunk is out of date and needs updating or removal. I'd say remove it.

[mwtoews]

I'd say merge any valid details to README.postgis, then rename README.postgis to simple README, without an extension.

It's a minor detail, but GitHub (i.e. ​https://github.com/strk/postgis) scans for a README file to display when viewing a directory (e.g. ​doc/ has a README).

[mwtoews]

I've attached a patch that would move content to the README.postgis (or README file, if moved). Please revise the patch at #1670 to make sure I moved everything important. I remove the GDAL Python bindings, since that's old stuff.

I recommend keeping bits of this file, moving it to raster/:

svn move README.raster raster/README`

Two things:

-No more need for GDAL binding

-Add a note on some of the variables we have to set (just in certain environments? like Windows?): PROJSO, GDAL_DATA, any other?

[pracine]

Just a not to warn you that I will not touch this. I consider this more in court.
