[vimgadgets-dvlp] New version of EchoFunc

[Yongwei W. <wuy...@gm...>]

I made some improvements to use the tags language field, so that I
will not use the C/C++ systags when editing a Vim file.

Changes:

(g:EchoFuncLangsDict): New variable to map the Vim file types to tags
languages that should be used.
(g:EchoFuncTagsLanguages): Rename to `g:EchoFuncLangsUsed'.
(g:EchoFuncLangsUsed): New variable: default values are from
g:EchoFuncLangsDict.
(s:EchoFuncDisplay): Use the tags language field and compare it with
g:EchoFuncLangsDict when it is available.
(s:CheckTagsLanguage): Use index() instead of count() for efficiency.

Best regards,

Yongwei
