Bootstrap script problem with special names

[hatamiarash7]

The bootstrap script has a problem with names that contain the word quack.

Suppose we want to have an extension called testquack, after using the script we will see something like this:

#ifdef EXT_VERSION_TESTTESTQUACK
    return EXT_VERSION_TESTTESTQUACK;
#else
    return "";
#endif

This happens because everything happens correctly on the first attempt to replace the words. But on the second run, the replace_everywhere function causes the replacement to be done again because the quack phrase is still there.

EXT_VERSION_QUACK -> EXT_VERSION_TESTQUACK -> EXT_VERSION_TESTTESTQUACK
