Improvements and fixes

• Improved the structure of the CRM export.
• Improved how eSignature requests show when an eSignature document is inside a folder. Now the folder also has a circle in front of it that makes it clear that the folder contains an eSignature file.
• Redesigned and simplified the Customization Settings page.
• Updated the welcome video shown to customers that haven't setup their portal yet.
• Fixed a bug that prevented large numbers to render in a single line on invoices.
• Fixed a bug that prevented the invoices status to update right away when sending an invoice from the client details page.
• Fixed a bug that incorrectly ordered Global and Local Extensions in the sidebar.
