[PATCH] perf tools: Add gtk. config option for launching GTK browser

[Namhyung Kim]

From: Namhyung Kim <namhyung....@lge.com>

Add config option for launching GTK browser for the specified command
by default.  Currently only 'report' command is supported.

Adding following line to the perfconfig file will have a same effect
of specifying --gtk option on command line (unless other related
options are not given).

$ cat ~/.perfconfig
[gtk]
report = true
