Pull Request: Add %fbase format specifier, allowing short "root" filename. Like %file, but not the full path, only the basename.

Add VRegistry::clearModules() to allow for runtime vmodule changes
For example, a signal handler (or some other runtime event) can
cause a loading of a "vmodule" specification into a string, and passed
to VRegistry::setModules().  Without a VRegistry::clearModules(), new
vmodule specs are appended onto existing verbose logs.  With it, eg.:
  void log_sighandler(void) {
    const char * newVmoduleSpec = ...
    ELPP->vRegistry()->clearModules();
    ELPP->vRegistry()->setModules(newVmoduleSpec);
  }
Can allow dynamic changing of verbosity levels of modules.

(Strictly speaking, only ca16478, but they're all tied together)
Add %levshort format specifier, allowing an even shorter log level.
The preconfigured log levels are uniquely identifiable via just one letter!
Therefore, only one letter is needed to indicate log level.
This allows even closer log output compatibility with an alternate logging
libary.  (If log parsing tools were already developed for said alt.logger,
this change makes the change to EasyLogging++ that much more seemless.)
