Minor Bug on variable numEnabledPageears

There is a minor typo bug on one of the functions that updates this variable. The module works fine but one of the performance improvements would not work with that bug.

On pageear.install file on function pageear_disable there is this code:

  // Update the global variable numEnabledPageears that tracks number of pageears enabled
  variable_set('numEnabledPagears', 0);

that has a typo on variable numEnabledPageears. The code should look:

  // Update the global variable numEnabledPageears that tracks number of pageears enabled
  variable_set('numEnabledPageears', 0);

I fixed it, I decided to add a hook_enable too to reset that variable to 0 when the module is enabled and I'm going to commit an RC5 updated version.

For those who had installed version RC4 would be desirable if after updating to RC5 they could disable pageear module, reenable it again, and after that, reenable the pageears you need enabled.

Sorry the inconvenience.
