Attach category to account

[mtotschnig]

From user:
I am having big list of categories created by me and all categories are listed in any account when adding entries, but most of the categories are not relevant for specific account.

Ex: for life expenses account, the lodging exp is not relevant. for tours and travel, the home loan/tax expense is not relevant.

If attach the required categories to relevant account, then it will easy to select categories from short list.
