fix seeding for seed = 0 (random seed from TUUID)

 Use TUUID to generate 3 unique seeds for TRandom2.
TRandom2 os then used for generating random states for both TRandom1 and TRandom3

TRandom is now initialized using the lowest 4 bytes of TUUID

This fixes the bug reported in https://savannah.cern.ch/bugs/?99516
All the 4 generators now pased the test reported by  Chris (see bug report)

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

Use double precision in return types and all arguments
of the random number generator classes. The modified prototypes are:
   virtual  Int_t    Binomial(Int_t ntot, Double_t prob);
   virtual  Double_t Gaus(Double_t mean=0, Double_t sigma=1);
   virtual  Double_t Landau(Double_t mean=0, Double_t sigma=1);
   virtual  Int_t    Poisson(Double_t mean);
   virtual  void     Rannor(Float_t &a, Float_t &b);
   virtual  void     Rannor(Double_t &a, Double_t &b);
   virtual  Double_t Rndm(Int_t i=0);
   virtual  Double_t Uniform(Double_t x1=1);

 Note that in case of Rannor, two functions are provided, one with
float and one with double for back compatibility.
