Autotests: Macro: Connection rules for CHEMS monomers

[AlexeyGirin]

Description:
These bunch of tests validates that system able to establish connections for CHEMS monomers
Related implementation tasks: #2925, #2883, #2334
Required monomers could be taken here: Monomers.zip

Test case1:

If a user tries to connect 2 monomers that have only identical free attachment points (for example, R1 and R1 or R2 and R2), a bond is created, and a message occurs.

Test case2:

If there is only one free attachment point (R1…Rn), a bond is created by default using only one existing possibility to connect to another monomer (no modal window appears).

For each %CHEMSType% from list: (R1) - Left only 
                                  (R2) - Right only
                                  (R3) - Side only 
                                  (R1,R2) - R3 gap 
                                  (R1,R3) - R2 gap 
                                  (R2,R3) - R1 gap 
                                  (R3,R4)

                                  (R1,R2,R3,R4,R5) 

	For each %MonomerConnection% (avaliable connections of monomer)
		left it unoccupied and occupy the rest
		For each %Test-6-Ch-ConnectionPoint% of Test-6-P from (R1, R2, R3, R4, R5)
			Establish connection between Test-6-Ch(%ConnectionPoint%) and %CHEMSType%(%MonomerConnection%)
			Validate canvas

Test case3:

User drags a bond from the center of the first monomer to the specific AP of the second monomer.

For each %CHEMSType% from list: (R1) - Left only 
                                (R2) - Right only
                                (R3) - Side only

		Select R1 of Test-6-Ch and establish connection
		Validate canvas (Connection should appear)

Test case4:

If selected attachment point is occupied, no bond is created, and warning message appears.
