Online installer: general modifications, addition of the metagenome data group

Modify the "Select Components" page of the "Unipro UGENE Installer Setup" wizard of the Universal package.

On all OS:

• Rename "Full package additions" to "Full package additions (include some NGS tools)".
• Rename "NGS package additions" to "NGS package additions (protein-DNA interactions)".

On 64-bit Linux and Mac OS X only:

• Add a new group (with a check box) called "NGS package additions (classification of metagenome data)".
• Add the "Taxonomy classification" item with a check box to the group. The item should be disabled and checked, if the "NGS package additions (classification of metagenome data)" item is checked or partially checked (i.e. a child item of the group is checked).

Taxonomy classification
The taxonomy files should be downloaded from NCBI, see items 1-6 in the links table in "Data Downloading" chapter of the Stage I specification.

Installation folder
Unpack the data, downloaded with the online installer to the "data/ngs_classification/taxonomy" subfolder of the UGENE installation folder.
