:LeaderfHelp only shows help tags for installed plugins under the home directory (~/.vim/...)

Steps to reproduce

Execute :LeaderfHelp

Actual behaviour

Shows help tags for installed plugins under the home directory (~/.vim/...)

Expected behaviour

Shows all help tags including /usr/share/vim/vim80/doc/tags

Steps to fix the problem

in helpExpl.py change line 32:
with lfOpen(tags_file, 'r+', errors='ignore') as f:
to
with lfOpen(tags_file, 'r', errors='ignore') as f:

The 'r+' tries to open /usr/share/vim/vim80/doc/tags for reading and writing which causes a IOError: [Errno 13] Permission denied exception.
The 'r' opens the file in read only mode which then works as expected.
