* Other minor bug fixes

## PGS7.17.0918

General Improvement:

* Most of the computations are multi-threaded, which drastically increases the speed
* Viewers generated from spreadsheets are new tabs within the same window frame by default; viewer windows can be docked back to the main window frame

* Apply button are removed from most of the dialogs
* Improved interface is cleaner and more user friendly
* New functional normalization method in the Illumina methylation array importer (450K and 850K)
* Improved SWAN normalization in the Illumina methylation array importer
* Allows import of different versions of the Illumina methylation arrays when using the same set of library files
* Improved text file importer by adding wizard for specifying the properties of the spreadsheet
* Removed repeated measures menu option, it is recommended to use ANOVA doing repeated measures analysis
* Simplified menus and dialogs, removed obsolete functions, improved wording
* Automatically downloads annotation files, even from sites with HTTPS or redirects (e.g. Affymetrix and GEO)
