Added acsessnthmon patch

TAGKEYS is a bit messy because #define is a preprocessor directive so we can't use preprocessor directives like #if to dynamically define the macro.

As such to maintain cross patch compatibility across the combo, swaptags and tagothermon patches we end up with 8 TAGKEYS definitions to cover for all combinations.

#if COMBO_PATCH && SWAPTAGS_PATCH && TAGOTHERMONITOR_PATCH
#define TAGKEYS(KEY,TAG) \
    { MODKEY,                       KEY,      comboview,      {.ui = 1 << TAG} }, \
    { MODKEY|ControlMask,           KEY,      toggleview,     {.ui = 1 << TAG} }, \
    { MODKEY|ShiftMask,             KEY,      combotag,       {.ui = 1 << TAG} }, \
    { MODKEY|ControlMask|ShiftMask, KEY,      toggletag,      {.ui = 1 << TAG} }, \
    { MODKEY|Mod4Mask|ShiftMask,    KEY,      swaptags,       {.ui = 1 << TAG} }, \

With this patch as-is if one were to enable only the accessnthmon patch then one would no longer be able to change tags using MOD+# as it skips the view binding.

Besides that properly integrating the accessnthmon patch into TAGKEYS we would have to cover for all the possible patch combinations and we would end up with 16 TAGKEYS definitions.

In practice there isn't any real reason why the focusnthmon and tagnthmon bindings would have to be in the TAGKEYS macro - unless most users have 9 monitors that is.

If there is interest in this patch then I can add it, it is just freestanding functions after all. I'd add them in separate files under the patch/ directory in that case.
