Some download paths have changed for (old) dependencies - fixed

• googlecode is deprecated, moved to github
• Qt5.2 moved to download archive

both checks failed for win64 with

Program: Z:\home\travis\build\dashpay\dash\dash-x86_64-w64-mingw32\src\test\test_dash.exe
File: random.cpp, Line 89

which is "assert" line here:

void GetRandBytes(unsigned char* buf, int num)
{
    if (RAND_bytes(buf, num) != 1) {
        LogPrintf("%s: OpenSSL RAND_bytes() failed with error: %s\n", __func__, ERR_error_string(ERR_get_error(), NULL));
        assert(false);
    }
}

i.e smth wrong with openssl.

On another note all other jobs in travis builds succeeded 👍
utACK

Maybe backporting this will fix it?

There is a fallback to OS RNG in btc 0.13 which we don't have and most likely there are also some other changes related to this, so I wouldn't mess with that too much tbh.
