bug: Fix and update translations

[DSCaskey]

This PR updates and fixes the translations in Seamly2D & SeamlyMe.

Fixes:

• Adds the qtbase ts files so that QT base widgets, such as standard buttons in dialogs are translated.
• Adds the folder ../libs/vwidgets so that classes in this folder are translated.
• Adds tooltip translations for the reset and savePreset buttons.
• Adds true flag to UnitsToStr() in the dialogtool class so that the units suffix string is translated in the tool dialogs.
• Adds translation to the "Toolbar" menu.
• Adds translations to the Shortcut dialogs in Seamly2D and SeamlyMe
• Correctly translates in the About dialogs "unknown" in the build revision if unknown.
• Changes the FileDialog in SeamlyMe to DontUseNativeDialog.
• Adds translations to the Utilities Calculator.
• Now retranslates the UI if a userchanges the language while in SeamlyMe without having to restart SeamlyMe.
• Removes unnecessary translations for qDebug() messages.
• Now Clears status bar help message when slecting the Export tool in Draft or Piece mode.
• Fixes a few QString related warnings. Such as helpLabel->setText("") should be helpLabel->setText(QString(""));
• Adds Tabloid, AnsiC, AnsiD, AnsiE paper options.
• Removes the min() / minimum() function translation in French. (issue BUG: function min() or minimum(); There seem to be two names for the same function, each half implemented #428)

Update:

Update languages:

• Spanish
• German
• Dutch

Add Languages:

• British English
