Toooooo slow vimwiki because of nested_syntaxes.

[GoogleCodeExporter]

I find vimwiki so slow ..., it need almost 2 minutes to open a vimwiki file, 
whatever it is new file or existed file.

Then I come up with --startuptime option, but this can now help me, it can not 
tell me why open a vimwiki file is so slow, instead of open other files are not.

Then I try to debug my tooo big vimrc by myself, (I thought maybe my some 
plugins conflict with vimwiki, or spent too much in vimwiki... etc)

I *really* forget how to find this, but I removed some nested_syntaxes, then I 
use command `$ time vim vimwiki/index.wiki +q` command to test the time after 
changes.
This reduced the time !!!
Really ...., I do not know how to say that .... This slow problem troubled me 
for a long time.
I almost added 10 nested syntaxes.

I think vimwiki should change the way of loading nested syntaxes.
e.g. seek for `{{{python` in file to determine what syntax to load.
Even this will lose a feature, This will not syntax highlight for a new edited 
file, this highlight only for an exist and already edited viwmiki file.
Really hard to decide.

Could you attach an example wiki file and vimwiki settings you use showing how 
slow vimwiki is?

I have found the reason:
html, css, php, those three syntax is very large, so vimwiki is slow if I add
those three syntaxes into nested_syntaxes option.
Solved it now.
Maintainer can improve document with adding this into FAQ.
