Custom location of dictionaries

[zdposter]

Please allow to set custom location of (hunspell) dictionaries - I do not want to have the same dictionaries on multiple location.

What locations are you using? Maybe we could just add them for everyone if that makes sense. Also, which operating system? On the other hand, have you considered symlinking?

I use windows.
I did not consider symlink - IMO that is workaround. I prefer cleaner solution with config option.
Hunspell is used these projects I use regularly: libreoffice, chromium, firefox, thunderbird, notepad++ (maybe more).

Hunspell checks for env variable DICPATH + it looks at many different locations (hunspell.exe -D):

SEARCH PATH:
.;;C:\Hunspell\;C:\Users\USER\Application Data\OpenOffice.org 2\user\wordbook;C:\Users\USER\AppData\Roaming\LibreOffice\4\user\wordbook;C:\Program files\OpenOffice.org 2.4\share\dict\ooo\;C:\Program files\OpenOffice.org 2.3\share\dict\ooo\;C:\Program files\OpenOffice.org 2.2\share\dict\ooo\;C:\Program files\OpenOffice.org 2.1\share\dict\ooo\;C:\Program files\OpenOffice.org 2.0\share\dict\ooo\C:\Program Files\LibreOffice\share\extensions;C:\Program Files (x86)\LibreOffice\share\extensions
AVAILABLE DICTIONARIES (path is not mandatory for -d option):
C:\Users\USER\AppData\Roaming\LibreOffice\4\user\wordbook\standard

I think that it would be nice to add these here:

spellchecker/jupyterlab_spellchecker/dictionaries.py

Lines 21 to 23 in 05487e2

	'Windows': [
	# TODO - contributions welcome
	]

Though we would likely need to do some variable name expansions to cover USERs and possibly allow glob patterns to allow for different open/libre office versions?

spellchecker/jupyterlab_spellchecker/dictionaries.py

Line 124 in 05487e2

data_paths.extend(OS_SPECIFIC_PATHS[system])

This looks good so far, the problem is to cover all possible directories for the different OSes. Linux is easy, but
for Darwin you have different ways to install the dictionaries, my dictionaries are in ~/Library/Spellchecker ... actually I don't have a clue how this can be addressed in Windows ...
