Prepare for coding sprint

Assumed:

• the usual build chain (gcc/clang, autotools, libtoolize, make/gmake etc)
• git
• editor, diff

Strongly recommended:

• master and SW git check-outs and builds (simultaneously): see Building Singular from source

Additional (for SW-related git repository), see also Development model:

• own github forks of Singular/Sources for exchanging code pushing & sending pull requests
• added TC remote repository for testing

Helpful:

• git GUI, e.g. qgit, sourcetree, tig or see http://git-scm.com/downloads/guis
• sdiff (belongs to diffutils) or vimdiff or kdiff3 or meld or p4merge or windiff etc.

Extra (for testing and debugging the differences between 32-bit and 64-bit builds):

• 32-bit build (for 64 native OS/builds)
