Document Project Generator / clean out old tools

Hey all

A few sections of the repo need some love to put them in line with the project generator:

1. Readme's
2. Rogue old project generators
3. Document complementing tools

Readme

The readme's in the root of the repo need some love
none of them mention project generator

i feel like each should be a description of how to get to a working project generator on each of the respective platforms

also note:

• .vs2010 is missing
• readme.txt repeats information from the other readme's (i.e. it's a list of platform specific instructions)
  i think this should be perhaps a little description of oF and a few tips on how to get started

Rogue old 'project generators' / documenting complementary tools for project generator

Here's things I can find in the repo which don't make sense to me at the moment:

• openFrameworks\scripts\????\compileAllExamples.bat
  ** is this supposed to be run (optionally) after the project generator?
  ** why is the project template within this folder?
• openFrameworks\scripts\????\createProjects.py
  ** if this isn't supposed to be used anymore, lets delete it immediately (we can always recover in emergencies)

and the 'other' folder in the root.. perhaps never took off?

Review the root README files, the missing .vs2010 reference, and the project-generator-related paths under openFrameworks/scripts, including compileAllExamples.bat and createProjects.py. Determine which generators and complementary tools are still current, then document the supported workflows and clarify or remove obsolete material, including the root other folder.
