Typo/spelling

[PaulPoulain]

There are some typo or spelling inconsistencies. This patch will list & fix some of them.

I'll not provide a patch, but show some inconsistencies & propose rules to fix them:

• be consistent in capitals. Sometimes we write "more options...", sometimes "New Resource". Proposal : Always use capitals (More Options, Edit Product Detail)
• validating a form is sometimes made using "Submit", sometimes "Save". Proposal: Use "Save". [except in new resource, where you have both, for a valid reason. And we should also change the wording for that one or add a hover info: the difference between "submit" and "save" is not obvious]
• Creating something is sometimes written "New" (New resource) and sometimes "Add" ("add new note"). Proposal: use Add
• sometimes creating something is spelled : "add new ". We rarely add an old info, drop one word ;-). Proposal: use "Add "
• the word "remove" must be used to remove something from a list (it's not deleted from the database). The word "deleted" must be used when something is deleted from the database.
