Uwe Stöhr 22cfcab074 installer: various fixed for immediate release
- LaTeX.nsh: fix bug that installer stopped working if LyX was installed the first time on a computer
- init.nsh:
 - fix failing installation of Slovakian spellcheck dictionary
 - expand list of available dictionaries as requested by users
- dictionaries.nsh: prevent case that the installer could run an infinite loop if the installation of dictionaries was interrupted
- settings.nsh: use a HTTP repository for MiKTeX instead of FTP because many companies deny FTP access by default in their firewalls
