Use of Annovar db & changed IC_template out info

- Removed hard coding of db used with Annovar. Instead user can supply a comma separated list of Annovar table names to use in the Annovar annotation.
- Added flag to list MIP supported Annovar db:s.
- Changed header and column info in IntersectCollect template after VMERGE to e.g. "outinfo:chr=>0_0,Start=>0_1 format" for readability. IntersectCollect stills supports outcolumns and outheaders format, but outinfo has been added.
- Added flag for maximum number of cores per node used in the MIP.
