2.1 fix linux

notes on how to run and build on linux and some small fixes for 64-bit

I will check the build errors, but Ive not needed to include the ignore errors flag in picross or strummer,
Id need to see why you are getting it, perhaps a different version of gcc?
which version of gcc are you using? ( Im using 4.7.2/Debian and 4.9.1/Ubuntu)

deb maintainer, I'll update

notes - yeah the issue is Python 2.7 (we use 2.5 on other platforms) , it appears to only load from the LD_LIBRARY_PATH, so currently Im creating a LD_LIBRARY_PATH which includes all modules, as I don't want to pollute the libs with the agent plugins. I suspect the mid term fix, is to dynamically add these directories at startup.

btw, if you need any help/info, you can email me (address on profile)... happy to help you get up and running :)

I'm running 4.8.2/Ubuntu.
It seems like reasonable errors/warnings, it seems a good idea not to cast int to pointers if not necessary.

I mainly had to give EigenD a try now that Workbench and Stage are also included. And it works well I must say, only it would be nice to update the readme a bit. Some later time I might connect the Striso to hear what that does.
