Disable magit auto revert mode.
Added manage-minor-mode package
Reverted back to using etags-select package for tag finding instead of
helm-etags+ because helm-etags+ can't jump to macro/define definitions
in Verilog. If the macro used is `XYZ, helm strips off the prefix
backquote and so the macro at point can't be searched in the TAGS file
Removed redundant code, used loop to sequentially call ctags for each
folder in tags-table-list in the build-ctags function.
