Haketilo

make Haketilo buildable again (for Mozilla)

How cool it is to throw away 5755 lines of code...

add actual payload injection functionality to new content script

add new root content script

facilitate caching repository responses in content scripts

test script blocking with and without the CSP-based approach on

move policy enforcing code to a new file, include basic test

fix license promise typo

utilize Pattern Tree to decide the policy to use and modify HTTP response headers according to that policy

This commit also enhances the build script so that preprocessor conditionals can now use operators '&&' and '||'.
The features being developed are not yet included in the actual Haketilo build....

reworked build system; added missing license notices

merge master (license notices) and koszko (v1.0 development)
