Add the ability to set flags via the config options api

Allows the setting of flags via the config options api.
For example, code like this:

#define OPT1 1 << 0
#define OPT2 1 << 1
#define OPT3 1 << 2

struct thing {
   unsigned int flags;
};

and a config like this:

[blah]
opt1=yes
opt2=no
opt3=yes
