improve wording in app

[ValentineHerr]

This is mostly stuff that came up during a meeting with La Red De Bosque Andinos...

• [x] make it more clear that you can upload multiple tables
• [x] make it more clear that the level of your data only refers to one of the tables but you can still upload higher level tables... not sure how to word that...
• [x] Identification depth --> determination rank?
• [x] tree --> individual
• [ ] "tag" vs individual ID withing PLot, Id with tree etc...
• [x] Propose to save profile before applying changes
• [ ] ...

• [ ] remove words like "local" and "global" in our own descriptions within the app
• [ ] be consistent in how the text is presented in IDs, always use "X within Y" structure, for all possible combinations of X in {stem, individual, subplot??, plot, site??} and Y = {individual, subplot??, plot, site??, whole dataset}
• [x] be consistent in how the text is presented in coordinates
• [ ] think what to do when the user has truly global coordinates (Earth) for each stem or individual
