Let SIGUSR1 trigger a reload
In an effort to better integrate the import process with external applications, it's desirable to have a mechanism by which external programs can trigger a reload of calcurse's data. This patch adds that functionality via SIGUSR1. The reload request is handled in the main loop. When the user is currently entering data, the request is delayed until the main loop is re-entered.
