[PATCH] increase the font size while printing profiles and dive information

[Lubomir I. Ivanov]

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

added the function set_profile_font_scale() in profile.c,
which allows to specify scale of the font before performing a plot().

increased the font size (FONT_NORMAL) in print.c to 30
