mFD 1.0.6

Fix bug:
- Correct the sp.plot() fct when plotting one asb (pb with vertices aes)
- Correct the sp.plot() fct when several sp same place but only one as vert

mFD 1.0.5

Fix bug:
- Correct funct.dist() function error when only quantitative traits (ISSUE 34)
Remove FSGE and FUGE from fuse() outputs

Add warning messages in funct.dist function: when using only continuous traits, no weighting is realised for now.
Add informations in the General Tutorial and in the Continuous Traits, no weighting is realised for now.
Fix bug:
- when computing FRic and FDiv but not enough species at different coordinates in the functional space to compute the convex-hull. Before it stopped with the error “Error in fdiv.computation(): Names of the vertices are not all present in species coordinates matrix. Please check.” as FRic vert were NA. Now FRic vert are NULL and pas the check.
- when computing FEs with fuzzy traits, attribution of species to wrong FEs, so when computing FEs, creating as many FEs as species.

Fix bug:
- scale center traits (parenthesis missing) in tr.cont.scale function
- correct FDiv legend in plot
- correct typo in Functional entities vignette

New vignette: create customised plots
Review mFD general workflow: fixed typos and missing chunks
Fix minor bugs in some functions:
- correct beta functional axes names, beta.multidim.plot() function
- correct check fuzzy names, check.fuzzy() function
Review function documentation
