Various problems with plugin config editor

[cavoknosig]

The plugin config editor has various issues referring to the correct cam sections (when defining multiple cams):

• With 2 cams defined, i'm unable to remove the "Send eMail with picture" tickmark on cam1 but keeping it enabled for cam2.
  Trying to save will always re-enable the tickmark on cam1, unable to remove the email part.

• It appears as if the two cam names are too similar, e.g. "cavok-doorcam" and "cavok-intercom" the plugin config editor has issues referring fields to the correct section. Edited fields in the email section for cam2 were stored as cam1 values and so on. If the cam name is clearly distinct, e.g. "intercom" only, function appears more consistent.

• Then tried deleting definition of cam1, which worked ok. All definitions of cam1 gone from the cfg file (when checking in the file manager) and the plugin config page starts with cam2. However, i then got about 25 Emails with an error "Cam [hashtag]1: E07: Cannot read camera model" despite only triggering cam2 url. Also, there is no way to reinsert cam1. Only a cam3 definition can be added.
