* R/shiny-ui-cmpd.R(server_cmpd): New server function.

* R/shiny-ui-sets.R(server_sets): New server function.

* R/shiny-ui-top.R(mk_shinyscreen) <plugin-servers>: Add server_cmpd
  and server_sets.

  new, updated data files observers.

In the current spirit of naming the observers in the comments, we are
listing the changes under their names inside the contex (angle)
brackets.

Note that some of the observers which were listed as "updated" may, or
may have not been created right now. It was too much to track.

* R/shiny-ui-config.R(server_conf) <update-files-on-restore,update-files-on-mzmlb>:
  New observers. They finally complete the data files modification,
  addition mechanism.

(server_conf) <build-config>: Updated.

(server_conf) <build-compounds>: Updated.

* R/shiny-ui-config.R(mzml2disp): Updated. Change levels to
  DISP_MODEMAP names.

* R/shiny-ui-config.R(combine_tags): Updated.

* R/shiny-ui-config.R <input$restoreConfB>: list2rev call removed.

* R/shiny-ui-config.R(ctrl2mzml_df, ctrl2mzml): New functions.

(get_all_sets): New function. Finally stopped recalculating sets.

* R/shiny-ui-config.R(get_tags_from_txt): Isolating input$tagsInp
  prevents fireworks.

* R/resources.R(DISP_MODEMAP): New parameter.

* R/api.R(verify_compounds, vrfy_conf): Updated.

* R/api.R(verify_data_df,verify_data): New functions. The first is
  used if the input is only a data frame.

* R/api.R(vrfy_conf,verify_compounds): Updated.

The observers are not really new, but is the policy to name the
observer in the comments for clarity.

* R/shiny-ui-config.R(build-config, build-compounds): New observers.

* (gen_cmd_inputs): New reactive function.

R/shiny-ui-config.R(server_conf) <build observer>: Emulate build
process from the cmd line flow.

* R/api.R <asserts>: file.exists -> isThingFile

* R/shiny-ui-base.R(txt2tags,combine_tags): Move
  to R/shiny-ui-config.R.

* R/shiny-ui-config.R(get_tags_from_txt): Turn into reactive from
  eventReactive. Will it now execute even when button non-pressed?

(server_conf) <rv$m observer>: Add tag handling.

(server_conf) <mzMLtabCtrl render>: Adapt to new tag handling.

Sorry :)

* R/shiny-ui-base.R(vols,vol_f,volumes): Obsoleted. Removed.

(mk_roots): New function.

* R/shiny-ui-config.R(get_proj_vol,get_proj_path): Obsoleted. Removed.

* R/resources.R(FN_DATA_TAB): New parameter.

* R/resources.R(EMPTY_UNK): -> EMPTY_UNKNOWN

* R/api.R(read_conf): The call of vrfy_conf removed due to some
  conflicts. Reinstate verification somewhere else.

* R/api.R(write_conf): Substitute conf with m argument.

(read_conf): Conflicts with the one in R/aip.R, so removed.

* R/api.R(load_data_input): Fix typo.

* R/mix.R(read_conf): Add defaults for mzml, known and unknown. Add
  tab empty list to out in m.

* R/shiny-ui-base.R, R/shiny-ui-base.R (rv_lst2lst, lst2rv_lst,
  rev2list, list2rev): rv_lst2lst -> rev2list, lst2rv_lst -> list2rev
