Excel (*.xlsx) Export/Import, Display Folder support, Small UI changes

[samsonfr]

Excel Export/Import

• Translation Builder always use comma as a separator which is not convenient for Canadien French computers (where semicolon is used because comma is a decimal separator).
• This version use the ClosedXml open source libray to Export and Import Excel files. When exporting it creates a real table that is autosized by column content and can be sorted/filtered.

Display Folder support

• Fixed DisplayFolder bugs : import from CSV and directly in the UI grid.

UI changes

• Changed default shortcut keys to avoid Ctrl+C and Ctrl+S which are usually associated with Copy and Save.
• A wait cursor is shown when importing translations from Excel
• Always show descriptions for Tables, Columns, Measures and Hierarchies

Sorry for the multiple Pull Requests ...

[jakeburns1]

Can you describe how this pull request handles the comma issue? Does the excel import/export fix that?

[samsonfr]

Yes by exporting to / importing from an Excel file it solves the comma/semi colon issue of CSV files.

Also, regular business users prefer editing in Excel than in a CSV file.

Do you think it's useful?
