Following new timeline aggregation were added:
* source and target port
* source and target type/tag
* detector type/tag
* protocols

I have implemented means for comparing 'aggregate' calculations within database with in memory calculations from timeline data, so that we can choose the best option.

For better performance it is now possible to restrict set of calculations in search form.

* devtools
* home

Custom CSS, JS and image files were moved to application`s static folder. (Redmine issue: #3443)

Fix: Disabled port and protocol timeline calculations and made adjustments to determine the reason for performance issues.

After deployment timeline calculations ware slow, possibly due to the unlimited number of items in each timeline bucket. I have added the limiting and removed ports and protocols from calculations to better inspect this problem on our development server. (Redmine issue: #3443)
