Add tag datatype (#698)

Browse Source 
Closes #680

Add `g:tagbar_show_data_type` field to show the tag datatype next to the tag in the tagbar window
This uses the `--fields=t` field to get the datatype from ctags. If not found, then it will attempt to derive the datatype by extracting all the output from the `pattern` preceeding the tag name.

More testing is needed on other languages. So far this has been stable with C / C++ files parsing the datatype from ctags output. It has also been tested with Java files for the inferred datatype by parsing the pattern line and pulling out everything prior to the tag.
