Merge ring bond count, degree and atomic mass atom properties

[AlexanderSavelyev]

Background
Right now it there are duplicates for the following properties

isotope=atomic mass
ring bond count = ring connectivity
substitution count=degree

Solution

• Rename Isotope into Isotope (atomic mass)
• Remove Atomic mass from "Query specific" and use the Isotope (atomic mass) field to load/save and display the atomic mass
• Remove Degree from "Query specific" and use Substitution count to load/save and display the degree. Display should be sn
• Increase number of options for Substitution count up to 9
• Remove Ring connectivity from "Query specific" and use Ring bond count to load/save and display the rings count. Display should be rbn
• Increase number of options for Ring bond count up to 9
• Increase all the "Query specific" properties which are drop-down up to 9. The same should be applied for right-click menu as well

The "H count" indicator in the "Query specific" section was increased only to 8, but it needs to be increased to 9 (as specified in the Solution section)
