installer: new method to install LaTeX-packages

LyX 2.0.x supports currently 147 LaTeX-packages. When LyX is first installed on a PC it took therefore about 10 minutes to install all supported and required packages. With the new installation method the installation speed only depends on the Internet speed and lasts with an average bandwidth now only 3.5 minutes.
(chkconfig.ltx asks LaTeX for each package separately and after each package installation the file name database of LaTeX was rebuild. And that cost a lot of time/CPU power)
