Rearrange verification jobs within presets
Currently there is a rather strange scheme of verification jobs arrangement within presets, it is according to directory structure and presence of some files. We thought that it would be better to have a verification jobs base that will describe everything required (job names, descriptions, tasks, etc.). Besides, there may be files and directories with rather complex hierarchy in addition to "specifications", "program fragmentation.json" and "verifier profiles.json" but they will not be used by Bridge. I suggest those directories will hold everything required for preparing build bases except for target program sources.
