Turn off first-time dialog from command line

[Peter Peterson]

Add a --silent option that can be set for testing for turning off the first-time dialog. It is very distracting when it pops up for unit tests.

re #10697 First time setup will not show if -qx or -s or --silent set

Changeset: 130be1916a441ca4b13011d9597a026a0abe961f

[Nick Draper]

New command line argument added:

-s or --silent: prevents the showing of setup screens (first time or paraview)

Also will not show if -qx used.

Also bug fixed that caused failure of mantidplot -h on windows.

To Test

1. If Mantidplot is not showing you the startup screen, bring it up from the start menu and remove the do not show again tick mark.
2. startup with mantidplot -s (no setup screens)
3. same with --silent
4. check documentation using mantidplot -h and http://www.mantidproject.org/MantidPlot:_Commandline_Parameters
