Patch from Roberto Vargas. »Add initialization strings in terminfo«

Taken from the description:

When tput init is executed the list of task performed are (taken from
terminfo(5)):

              run the program
                     iprog

              output is1 is2

              set the margins using
                     mgc, smgl and smgr

              set tabs using
                     tbc and hts

              print the file
                     if

              and finally
                     output is3.

When reset is executed, a more stronger initialization process is performed,
so the terminal can return from an unknown state. rs1, rs2 and rs3 are used
in this case instead of
using is1, is2 and is3.

This patch makes is2 = rs2, resets insert mode and set normal keypad
mode. For rs1 it performs a full initilization using ^[c.
