Couple of tile changes and some new styling

Release 1.2
Based on further user testing and feedback we’ve made the following changes: 

• Split Help me into two tiles:
1. Help me now includes links to ask.monash, service desk online, password management and defibrillator locations.
2. Search now has links to our four main search options: web, intranet, staff directory and my.monash.
• Consolidated maps into a single tile: Maps and locations
• Adjusted the styling of the tiles to improve accessibility and readability.

We’ll continue to work with our colleagues in Strategic Management and Communications (SMC) to ensure my.monash aligns with the new brand.
