Improvements and fixes

• Updated the client user invite flow so that accounts can be activated by clicking on a link vs. having to enter a code manually.
• All new users now have an icon that consists of the first letter of their first and last name. The icon is replaced when the user uploads a profile picture.
• Various layout improvements to improve the look of your Portal on larger screens.
• Improved tables so that they look better and load faster.
• Desktop-only pages now show a modal that informs you of this. Mobile support is in the works.
