Given a sequence ${a_n}$ with its first term $a_1=1$. The sum of its first $n$ terms is $S_n$, and $a_{n+1}=2S_n+1,n∈N^{*}$.

(I) Find the general formula of the sequence ${a_n}$;

(II) If ${b_n}=log_{3}{a_{n+1}}$, find the sum of the first $n$ terms of the sequence ${a_n}+{b_n}$, denoted as ${T_n}$.
