SciDAVis - Improvements SVN-temp

- Removed unused Table::columnNumericFormat() methods (small code cleanup).

- Improved performance of column formulas for large tables (fixes part of bug
#2778891).

- Changed filename of Windows installer to include the platform we're currently building for (win32).

- Added Brazilian Portuguese translation to Windows installer.
- Fixed run path of shortcuts generated by Windows installer.

- Added some missing tr()'s, and lupdate'd translations.

- Fixed crash when trying to acess non-existing column via MuParserScript.
- Improved pasting of cells from OpenOffice.org Calc and KSpread into tables.

- Brazilian Portuguese translation update; thanks to Fellype.

- Fixed setting of plot designation in Table.importASCII().
- QPrinter constructor is expensive, particularly on systems where this triggers
a network scan for available printers. We definitely don't want to do this on
every ApplicationWindow initialization (i.e., application start, new project
and open project) just to get a default export resolution. Having this depend
on the settings of the printer that happens to be default /on the first
application start/ (value will be taken from settings subsequently) is insane
anyway, regardless of performance penalty.
=> changed to hard-coded default of 72 dpi

- tagging version 0.2.2

- prepared release 0.2.2
