ozagordi/MinVar: MinVar 2 has HCV support

MinVar has undergone a substantial restyling, but the most important feature is that HCV support has been added. Mutations are called with respect to H77 strain. There is no need to specify which organism is being analyzed, it is automatically detected.

The creation of consensus sequence is more robust, the program should run slightly faster (more tests are needed) and the final report is both better styled and more customizable (documentation will come soon).
