Updated dynamic navigation bar and other minor updates

Updated the navigation bar code to not use the customJS plugin as it was causing errors to be displayed when the navbar is loaded on launch of Obsidian and occasionally on mobile devices. The README has been updated to reflect this change.

Minor fixes and new templates

- Fixed bug with Travel and Trips showing "maybe a file already exists?".
- Fixed external link that was broken.
- Minor modifications to style settings.
- Added new templates to allow for quickly inserting headers.
- Reorganized dataview and javascript files.
