Updated appIcons and appLogos for bubbles
Merge branch 'develop' into feature/bubbles

Pulled in latest changes on develop branch including released version 3.4.
Add Navbar color for bubbles.  New pan_overview dashboard using built-in maps.  Modified saved search for Top Applications to fit better in the new dashboard.
Converted all dashboard except NetFlow to SimpleXML (from AdvancedXML).  Note that the same search strings from AdvancedXML are used and drill downs are currently set to default.
Add drill downs to overview dashboard
Add protocol as searchable field in traffic overview
Update macros to include 'file' logs and removed 2050 log type.
Create a blank dashboard.css file to hold dashboard stylings.
CSS styles for SimpleXML dashboards
Rename pan_overview.xml to overview.xml
Update nav bar for new overview page and corrections to overview menu
Adjusted header names on overview application table to fit better on screen
Changes to dashboard forms, searches, and drill downs.
Added remaining drill downs to SimpleXML dashboards
Returned SimpleXML Traffic dashboard back to tsidx due to known Splunk issue (SPL-74415)
Fixed built-in Splunk 6 map on overview page so it doesn't rely on external geoip apps. Uses built-in 'iplocation' command.
Changed WildFire user drop down to a text field. There could be a LOT of users on some networks which would overwhelm the search if not using acceleration.
Added a Splunk 6 Data Model to represent the Palo Alto Networks log structure. Currently this model is NOT accelerated due to known Splunk issue (SPL-74415)
SimpleXML dashboards: Cleanup and correction of inline search strings
Changed default to null string for all SimpleXML forms
