Changed syntaxMap(lc_syntax, '').lower() to syntaxMap.get(lc_syntax, '').lower()

I was getting this error when trying to use a Capital name in the syntax map. 
Traceback (most recent call last):
  File "C:\Program Files\Sublime Text 3\sublime_plugin.py", line 255, in on_post_save
    callback.on_post_save(v)
  File "C:\Users\tyler.thrailkill\AppData\Roaming\Sublime Text 3\Packages\SublimeLinter\SublimeLinter.py", line 776, in on_post_save
    queue_linter(select_linter(view), view, preemptive=True, event='on_post_save')
  File "C:\Users\tyler.thrailkill\AppData\Roaming\Sublime Text 3\Packages\SublimeLinter\SublimeLinter.py", line 376, in select_linter
    language = syntaxMap(lc_syntax, '').lower()
TypeError: 'dict' object is not callable

This shouldn't have been happening, as far as I can understand. Upon changing it to .get, it seemed to resolve the problem.
