T1, TI and CT -> title in Mendeley

[customcommander]

The tags T1, TI and CT are mapped to title (in this order). If one exists all the other are ignored.

The following RIS file:

TY  - JOUR
T1  - T1 is 1st (I)
TI  - TI is 2nd (I)
CT  - CT is 3rd (I)
ER  - 

TY  - JOUR
TI  - TI is 2nd (II)
CT  - CT is 3rd (II)
ER  - 

TY  - JOUR
CT  - CT is 3rd (III)
ER  - 

Should produce three references:

1. title="T1 is 1st (I)"
2. title="TI is 2nd (II)"
3. title="CT is 3rd (III)"
