API does not handle more than 25 projects in Redmine

[dmigowski]

The problem seems to be the function Api\Projects.all(), which simply calls the JSON API which doesn't return more than 25 projects if no limit is given. With limit, it returns up to 100 projects. To really make this usable, someone should either add a limit of 100 there, or should do a series of calls until all projects have been read in.

fixed in #36,
@dmigowski you should now be able to pass an optional 'limit' param to all "all()" methods
