This commit enables colors in bmon. It adds configuration options to let the user decide, which colors should be used. Therefor the graph_rx and graph_tx layouts are introduced and applied respectively. * Add graph_rx, graph_tx and layout_cfg fields. * Setting default colors if colorized output is enabled. * draw_table accept additional layout parameter and apply the given layout for the table graph. * Apply layouts for rx, tx graph and header and statusbar. * Add include/layout.h, which provides functions to parse, color and attribute strings and set the layout. * Adding a default layout-config example in examples/bmon.conf. [Edit: Based on original work by eri!, #PR23]
