[PATCH 4/4] Profile: fix a couple of warnings

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

profilewidget2.cpp:1398:25: warning: the omitted middle operand in
?: will always be 'true', suggest explicit middle operand [-Wparentheses]

profilewidget2.cpp:1403:39: warning: comparison between signed and
unsigned integer expressions [-Wsign-compare]

Signed-off-by: Lubomir I. Ivanov <neolit123 at gmail.com>

mingw-gcc-4.8.2

the second one is reasonable, but i'm not sure about the first one.
the patch makes it safer, but uglier and slower if that matters.

please, discard or comment if see fit.
