Allow GO_Utils to be used in batch mode

The GO_Utils initialization relied on idc.here(), which when
run in batch mode would result in the following error:

Z:\vm\IDAGolangHelper-master\auto_go_rename.py: could not find segment at 0xffffffffffffffff
Traceback (most recent call last):
  File "C:\Program Files\IDA 7.0\python\ida_idaapi.py", line 553, in IDAPython_ExecScript
    execfile(script, g)
  File "Z:/vm/IDAGolangHelper-master/auto_go_rename.py", line 29, in <module>
    GO_SETTINGS = GO_Utils.GoSettings()
  File "Z:/vm/IDAGolangHelper-master\GO_Utils\__init__.py", line 15, in __init__
    self.bt_obj = Utils.get_bitness(idc.here())
  File "Z:/vm/IDAGolangHelper-master\GO_Utils\Utils.py", line 35, in get_bitness
    if idc.GetSegmentAttr(addr, idc.SEGATTR_BITNESS) == 2:
  File "C:\Program Files\IDA 7.0\python\idc_bc695.py", line 152, in GetSegmentAttr
    def GetSegmentAttr(segea, attr): return get_segm_attr(segea, attr)
  File "C:\Program Files\IDA 7.0\python\idc.py", line 3508, in get_segm_attr
    assert seg, "could not find segment at 0x%x" % segea
AssertionError: could not find segment at 0xffffffffffffffff

Even having the script Jump(BeginEA()) before initializing the library
would trigger this error occasionally.  Replacing idc.here() with
idc.BeginEA() resolved the issue.
