[RFC/Patch] Tool rename fallout fix

Immediately after I updated the "master" branch with the tool renames, I got a complaint from somebody telling me that the things do not work anymore without 'make install'.

Strictly speaking, git has never worked fully without installation because 'git' wrapper looked for things in the same directory as it was in, which meant that 'git applymbox' would not have worked anyway (it was coming from tools/applymbox until recently), but on the other hand it certainly is nice if we can run most of the things immediately after building but before installing.

This patch attempts to remedy it. What is helped the most is that test scripts do not have to special case the scripts anymore; obviously we do want to be able to run tests before installing. A downside is that your working tree after a build has a lot more files than before.

As a side effect, you can specify non-standard path your Perl is installed, and you can explicitly say "#!/usr/local/bin/bash".

Comments?
