Rewrote the shell_escape function in order to make us of GString and g_string_append_c

Browse Source 
As we decided to fully switch back to glb we needed to rewrite this function in order to use
glib functions. This means in this case mostly that *ptr = c; ptr++; is replaced by something
like this: g_string_append(str,c); with str a GString*.
